I don't see any immediately obvious damage to the engine, but then, you can't tell a lot by the pictures. Where's the crankshaft? Another club project candidate? The 575th production 150, and it IS the right year model!
When I found it I wasn't thinking of it as an aniversary cannidate. I noticed it was over in that thread. My guess is it is going to go around $4000.00 to $6000.00
