75 Husky 250CR GP with 74 CR400 motor. Barn Find!

I happened across this bike by chance. It is a bit crusty, but complete enough to be restored or used for parts. From what I can gather from various sources, the title says it all. The engine is stuck from sitting. I have not tried to free it up, as I have other projects. I just figured this bike deserved to be fixed up or at least used as a parts donor. No, I will not sell the engine or other parts separately, thanks. Detailed photos available by request. Located in Brookline, NH, USA. $600. Thanks, Bob
