Hi Guy's
Hi Ian,
I have been asked by Pat Slinn to do a bit of reserch,into the bike your father built.
I know it may sound stupid to you but what was your fathers first name.
Pat and I are reserch into anything to do with the BSA Comp department, so you may have found the right two people. We will see what we can do.
The front forks to me keeps saying Velocette? I know I have seen some like this before. Good line to throw us, over this time of the year.

Regards Charlie.
