Thank you Cobra, have it now[:)]
-
Thanks for the pic; a very early 4-cylinder (Anzani-engine), with single-pane windscreen (which has an exposed lower panel due to straight screen frame vs. curved bulkhead). No front wheel brakes, of course.
Good luck with your rebuild and please keep us up to date. What's that next to it, an Alvis?
-
Very nice Car indeed.
-
Yes next door 12/50 Alvis
Engine No 2237, has piston type oil pump, exhaust manifold integral with block and priming taps in the head. Car is some 200 odd earlier than the four seater that used to be at Beaulieu, yet was registered some weeks later, third quarter of 1921. Southampton registration, cast aluminum number plate bears a north London makers name.
Almost ready to build the engine, just working on a test rig to run the oil pump.
-
Another feature that ages this vintage AC is the U-shaped headlamp brackets. Early cars, like this, also had one door only and a central running-board spare wheel. Here's a pic, and specification, from the 1922 brochure (it should be readable but might need downloading and enlarging). Note the oil consumption quoted - 600 miles per gallon (= a pint every 75 miles).

Headlamps from this car have adorned the front of 31225 for the last 40 years-
The pistons have no oil rings, two substantial compression, then a groove with drain holes-
The residue of the oil in the sump stuck to your skin like tar, almost impossible to scrub off!
The valves have no guides, run direct in the iron block, unequal stem diameters, the inlets larger than the exhausts, perhaps Anzani's were using up old stock left over from their cancelled aero engine contracts. The amount of carbon deposit under the exhaust valve heads had to to seen to believe! Bit plasticy to not hard, benzol based fuels were popular I believe, not the volativity of today's fuel. I remember a picture of Birkin filling his Alfa during a TT, would be 1931 I guess, big funnel in the tank, emptying a churn into it, fuel sloshing all over and he has a fag in his mouth!
-
That is a very smart-looking car! A much later vintage 4-cyl, now with 2-doors, entry steps, and with the spare wheel mounted into the wing and running board. It has 4-wheel brakes, so probably around 1927 model and, interestingly, four stud hubs. Nice car Jonto!
-
I sold 31225 over 30 years ago, don't know who has it now, picture from the Bath and West Show summer before last. It is a 1927 car registered 1st January.
Connecting rod from the Anzani engine, minus white metal babbit bearing-
Crankshaft assembly-
-
Crankcase and sump, piston type oil pump operates from an eccentric on the camshaft via a push rod and return spring-

Great thread, please keep posting as progress is made! Graham.

It would seem that the AC in the top photo (CR6208) is the oldest surviving 4-cylinder Anzani-engined AC and, indeed, is the oldest surviving vintage-period AC. Earlier AC's; only the few pre-WW1 Fivet-engined Edwardians and the Sociables and Box pre-date it.
-
There may be an earlier car. I went with some friends in the 1970's to see one in the garden of a house at Neston on the Wirral, it had been replaced by a later car, a 1932 model I was told, I never saw this car as the owners were deceased and it had already been purchased from the estate. The earlier car had been turfed out into the open to weather the elements and was a bit distressed, I remember I could not find the car no plate but it was similar to the one I have so could have been earlier. I heard later that someone on holiday in the area was told about it and took the remains away, to Scotland I think.
-
Back to 6199. Here is the last tax disc the car wore-
Story is that the car was taken off the road because the engine was tightening. When I stripped it the big end bearings were mauled, the white metal cracked and breaking up. There was dirt in the sump, the piston type oil pump requires a none return valve to develop pressure, if there was dirt around and it was not seating there would be little or no oil circulation and I guess the big ends would be the first to suffer. The crankshaft journals are standard size 1-3/8th inch with little wear, same for the bores and pistons, 69mm.
-
Here's a rough assembly I did some time ago-
The car was at Little Lever a village near Bolton, Lancs, it was known to the locals but had not been seen for a long time. Then one weekend the local Milkman, Bernard Moynaham when calling to collect his money found the elderly owner in a talkative mood and managed to buy it. Later when he went to collect it he found the garage in a bad state and it had rained over the years, the body was beyond hope as were the beaded edge wheels, rotted where they had been touching the floor. So he passed it on to me as spares for the car I was running at the time.
-
Upperc rankase, sump.
Timing chest gasket, jut need to trim, the faces on the aluminum castings seemed to fragile to use the tap it out with a hammer method-
External drive to rotate the camshaft and thus run the oil pump to check its output-
I had to let a new piece into the nearside of the chassis frame, made new front engine plate and the two rear engine/front spring mounting plates but steering box plate is an original, from the late Hugh Lupton along with the well base wheels and other useful bits.
-
Crankcase with shaft.
Oil pressure test, relief valve opens at 20psi.
-
Cylinder block and head.
-
Great job of posting pics! We need more like you to share their interesting projects and details! Thank you!
-
I'm enthralled by your project. Keep it coming!
:-)
-
Anzani the right way up at last-
...hope I put the crank in the right way up, one speed forward and three in reverse [:0]
-
Anzani valve gear, roller cam follower, peg valve collet.
-
Engine back in its rightful place, with a lot of help from a good friend who's done some nice detail work-
-
Transmission, axle has three sets of numbers-
F815
G1042
6573
-
Next, the clutch, here's the parts-
Bottom right, the tubular steel part screws on to the crankshaft and doubles as a flywheel nut and support for the cast aluminum clutch plate which is bushed and runs on the outside. This provides the idler bearing that takes up the difference in speed when the clutch is parted. Bottom left the double helical spring lives inside the tube and thus is out of sight when the clutch is assembled
-
Drive shaft, clutch to universal joint-
The square tooth coupling on the right takes the drive from the clutch, then below the clutch fork and thrust bearing. Above the steel disk is a clutch brake, then left the universal joint blocks and spider. The whole shaft moves back to open the clutch, the sliding block universal joint taking the movement.
-
Clutch and drive assembled, pedals and linkages-
-
Claudel Hobson barrel throttle carburetor and throttle pedal-
-
AC's own built worm and wheel steering box, hand throttle and ignition levers-
-
The beginnings of some coachwork...
Assembled the steering gear, just under three quarter turn on the wheel from full lock left to full lock right!
-
Next the rad. Has any one had a vintage radiator re-cored, any recommendations?
-
I was going to do this on my Swift,but decided against it as there was a long waiting list from the preferred repairer,and its very expensive.
I decided on using Fernox central heating system cleaner ,sitting in rad then power washing out. I then used "alumaseal" for any small leaks as its a low pressure thermo siphon system. Luckily my radiator was servicable.
The name of the repairer escapes me but they are in the back of the "automobile" magazine.
Steve Gray ,AC Heritage may also know having prepped his car for Peking Paris.

I have two radiator's. the original one to the car, there is corrosion of the copper core, the second one is in a better state except for crushing at the bottom where vandles had tried to wrench it from its chassis. So I have to have a rebuild, has anyone had the work done and has any recommendations?
-
I was at Lowton Park yesterday, the ex Condon 1924 12hp was there now in the hands of Kieth Hill. I learned that a vintage radiator has been successfully rebuilt by a firm in Wakefeild, I'll make inquiries there.
-
Two possibles are:

-
The radiator is now away for the rebuild, it will be some time.
-
I have not posted here for a while, but work has continued, fuel tank, windscreen, dash and instruments.
Does anyone have a picture of the three seat "cloverleaf" model that was available 1919/20? I believe one is featured in an article in the Light Car and Cyclecar of the period.
-
New silencer from the exhaust shop [:D]
-
Steering gear and exhaust installed.
-
Jonto, could you let me know the company that made your silencer. Send me a pm if necessary.
Many thanks!

John.
Just an Idea, Fire a email with a link to Simon Taylor. As well as being a Mine of information, associated with motor journalism, he is also a ACOC Member ( 2.6 Ace ) and has a massive reference library.
If he hasn't pictures and details, maybe he could put a request in a future issue of Classic & Sports Car...[;)]
Will confirm his email address and tel number via email. [;)]
Great thread, following with interest and looking forward to seeing this AC on the road.
Cheers for Now
Keith
-
Perhaps try the VSCC library at Chipping Norton?

1919 LC&C and Cloverleaf model is on the list to investigate at my next visit to the British Library. They claim to have a copy of every British magazine ever published - and so far have not failed!
Regret Burnard's papers are not in the ACOC Archive

I hear the radiator rebuild is done now ans it should be back with me in a few days.
-
Well its running, after 85 years in hibernation.

Although I couldn't see you photos for some reason, I congratulate you on this fantastic achievement!
Thanks for posting.
-
Its a video, struggling to add it!
-
All working well now, though!
-
Wanted to display the video on these pages, but cant manage to do it.
-
Most sincere congratulations, thanks for sharing, greatly appreciated.
-
My attempts at a "three seater", have to teach myself panel beating now!

Not powering an AC but another famous Anzani engine running-

Door lock, handle, aluminium switch box and bezel wind clock.
-
Update, progress, ready for panelling now.
-
Side view-
-
Rear-
-
Ordered aluminium sheet for the body panels, new area for me, but gotta do it!
-
I'm still working on it, but bodywork is a long winded job, when your not quite sure how to do it!
-
Sometimes it seems you have taken a step backwards-
-
It feels like your doing a fitting for a bespoke suit-
-
Still a lot to do, shaping up, beading.

Done a bit more, beading to the panels, running boards and spare wheel mount, though I'll need more timber for the boards, dimensions are a bit guess work first try!
-
Update, no so much to do now, I have some rear wings I can use, but no stays, conversely, I have the stays for the fronts, but no wings :)
-
.
-
Update, the bodywork is not far from completion now, I am currently working on the mudguards.
-
Getting there.
-
Great looking machine, she will be loads of fun

-
A bit more progress. The early type windscreen and CAV "Torpedo" lamps.
-
It's coming along Jonto!
-
Something to be very proud of - well done
Barrie
-
Many congratulations, the dash looks wonderful too, is it the original?
-
No I have the original, this is one I found at Beaulieu many years ago, its the same, I have the original but this has less holes. It was fully instrumented too, some handy spares.
-
I have some parts that I do not need. Four cylinder bonnet top, couple of four stud wheels, some rear brake shoes large drum, and more, I'll get around to listing them sometime. Anyone have a couple of bonnet handles they dont need?
-
I could well be interested in the bonnet top as mine is a home made affair, sorry I do not have any spare bonnet handles,
