Got an early crankcase for $20 and $18 shipping. Got a deal from the same seller for the transmission and fork drum at $10 each. Good bargain. And now I have a bona fide early style engine to either rebuild (if you could find the gaskets) or just for reference.
Seller even included a few other bits and bobs that weren't listed. The packaging... no other word for it than "professional". He glued strips of cardboard to hold everything tight and in place. Impressive.
