Also have two project bikes...an '82 GS750E and a '41 BSA M20
Let's see the M20.
Here's my (mostly) WD M20 from 1944.
The engine, transmission, oil tank, primary, front frame loop and front end are original. A previous owner put the plunger rear section on. I came up with the tank, seat, bars, headlight, wheels and fender. Nowhere near orignal but it's fun to put around on.
