Obviously this is past the registry of who owns what by now.
Below for first gear clutch drum and shoes, the one on the crankshaft.
The blade and fork are one way 360 and 390 and the other way 420, 500, 430. I am pretty sure the engagement mechanism changes at this point. I am talking about how the shoe attaches to the center.
The shoes are bronze or similar with ridges at a slight angle 360.390,420 and smooth and magnetic for the ones with the starting pawls, 500. 430.
The drum is smooth inside for the bronze shoes and has a spiral cut into it for the 500,430. The shoes clearly have been drilled to achieve some balance.
