As there has been a number of suggestions and expressions of interest I thought to see exactly what I have. So I trekked up to the hay loft to investigate: There are 27 windscreens, all Triplex, heated and Sundym 'tinted.' This colour is standard for MEs - it looks like a tint, but is some sort of clever UV limiting formulation. The heated element is not standard on the Mk.1 ME, but would have been on the MK.II hence all these 'screens being in the Triplex warehouse in Glasgow. They will fit straight in to all MEs. Each screen has two heating panels, from memory 10 amps each, so a couple of sturdy wires for 12v feed and two more to earth should see you de-iced and demisted. Not that the electric supply is mandatory of course. The Triplex system is not long lasting and you might just install it without connecting the heating. I remember on 169 that it was very useful, but within two or three winters there were individual heating elements in each panel which had gone open circuit. Personally I would take the trouble to add the wiring, relay and a switch, with a warning light, whilst fitting the new 'screen.
All this glass together is quite heavy, but it would go in a decent estate car or Range Rover. I rather have my doubts about a pallet service as damage would all too easily occur. Anyway I will be pleased to fit in with any plans, if you have an urgent need I'm afraid you will need to do some long distance driving.
