Probably a scam - this car was the subject of a forum "Topic: Greyhound for sale on eBay - running project" a little while back. The car was originally sold on Bring a Trailer in 2017.

Many thanks Old Crock, that's exactly what I needed.

I do not know how to put a link in the forum correctly but I just came across this Greyhound project from a private seller in France for 36,000 euro.

Wow, Jonto, that is one potentially 'prize-winning' silencer!

Galfredus, re your last posting. See photos attached, you can download and enlarge:

(1) shows a silencer on an AC Six, front end. Clearly not a new one, nor a direct copy of an original, this had a hole in it but it shows the mountings and the positioning on the chassis (relative to other parts and fittings) 

(2) Rear view

(3) poor sketch, but shows all (rough) measurements that I used to replicate an original silencer

Dear all,

Many thanks for your advice on this.  It's often the things that appear the simplest which turn out to be the hardest.  It's no great surprise though - the things that were missing when I bought the car seem to be the things which are hardest to find!  I certainly do not have the pipe bending facilities or fabrication skills needed to do this myself. Will have to look into bespoke options I think.

The car isn't currently in my possession so I can't check details.  I take it the silencer is mounted towards the front of the car where the twin pipes from the manifold bend under the bulkhead?  Can anyone provide me with the dimensions (length/diameter) of the silencer?

Many thanks,

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!

Made up this silencer for my 4 cyl, built up oversize the cast iron ends and used them as patterns to cast new end pieces in bronze, the body is stainless tube, through bolts stainless bar, nuts at each end. Instead of fitting baffles, I have the tail pipe extending into the silencer interior about half the length of the silencer, with the end plugged and small holes, perhaps 3/16" drilled around the pipe diameter, enough to equal the pipe section area. You can experiment with more or less holes if you wish, as this has some effect on the mixture. Your on SU's, remember the jet adjustment is for slow running only, changing the mixture on throttle open requires new needles to a different taper. I have a nice "ring" to the exhaust note and its not to loud.

Depends on your enthusiasm, workshop equipment and personal skill.
If all are good and you have a manifold already to work from then go to a local exhaust suppliers after a quick measure up and ask to walk round and look at what they have. There is always some really inexpensive bits that can be chopped and mated to make up a system.
If all are lacking and you are looking for a top notch full flow system including shaped manifold and down pipe and you live close to Leeds then try TLE (Tony Law Exhausts). (Sorry don’t have a link).
If you want a slightly less expensive option but still done by others then you could get to know a friendly independent exhaust fitter. He may fancy something a little different than the usual humdrum Corsa or Focus and see it as a bit of a change to expand his horizons and find it interesting to cobble something up.

Thanks for the interest and speculation.
Carburettors are the only modification  from standard 100D2 spec.
Camshaft was checked and fine at time of head overhaul and springs were tested. Inspection now shows springs ok. Problem happened at a modest 3500 rpm. so bounce should be relevant
Valve clearances were checked less than 1000 miles ago and are standard at 2 thou. cold. My Bristol Engine Manual states that this will result in a running clearance of 8 thou. So more likely to drop out when hot.
Nick Finberg from Classic Autos has never heard of it either. 
Joe at Moto-Lita has all my steering measurements and is making a custom boss to fit so I can use the 16" wheel.
Will keep you all posted...
