Have this Cutaway BSA found in a motorcycle show in Maine and as I am progressing redoing it, I was wondering what the original colour of the rear foot rest would have been. I don't know if it is the original British no 3 or some later version of a post war repaint
Here are some of the work done already. Gearbox and timing cover are not of the cutaway as the original were missing. Oil tank does have its side open for viewing
Spark plug is incorrect on this one

You've certainly got your work 'cut-out' there. 
I thought I'd say it before anyone else did. 
Interesting way to build a "chopper"
