I love that spring! Brilliant!

I knew that I'd seen the engine somewhere. On ebay earlier this year:-
Complete and ready for collection
Vintage 1930.s 750cc V twin Sturmey Archer as fitted in Raleigh safety seven two seater sports car, interesting engine for special/three wheeler, alloy heads, 3 speed gear box, self start + handle, coil ingnition/dynomo, no broken fins or damaged caseings. internally very good except some wear in cylinder bores.
I bought this for a trike but too many projects.... and someone bought the Raleigh on ebay recently. They might want to revert it to more original than the Ford 100e engine they have ??
As you said morrag, they wanted serious money. More than I could afford for an engine and box but would be perfect for a period reverse trike
