My mate has found some girder forks in his shed from years ago when he used to do auto jumbles. He thought they were M20 but some differences have been pointed out. They look like BSA forks to me, but what model?

Yes BSA! Not M20.....But what model? So many to choose from. Leon is probably the best person to ID them. Ron

It's early to mid 1930's.
The two bolts in front are for the speedometer bracket.
Nice find.

Yes, it don't has the brazed attachment for the large 7 inch brakeplate so looks like a lightweight, 250, maybe like the B3 from 1933.

There could be a partnumber on the front of the central mudguard attachment.

Michael is spot on, Leon has said they're off a 1933-34 lightweight and middle weight BSA :slightly_smiling_face:
