I got the correct engine number from Bob today - so a minor re-edit....
Im trying to help out my friend Bob - fellow sandcast restorer. He is after a Sandcast frame in the 1900-2500 range to match his #2189 sandcast engine. Or he would also consider a deal swapping his fully reconditioned #2189 engine for a good matching set of Sandcast Frame/Engine or partial bike. His engine work is top notch and uses the machine shops with the best reputation local to us.
If you want more information pls contact me and I can organise photos etc.
Thanks,
Steven.
