I had bought end of last year a 350cc Douglas 1930 H3, nearly complete, but main parts of the engine missing.
The engine had in the 1950ies a broken crankshaft, was dismantled and most engine parts getting lost.
I had the luck to buy a ER stamped engine (right for the model!) at Ebay, but this engine is in a bad state and several parts are worn.
I would like to get a flywheel and hope someone can help.
Also the taper end of the crankshaft is worn.
