This frame kit was jigged and copied from an original BSA works frame.

Information on these frames is very scace and many people claim the GP Victor was the works bike.

If you know what to look for it's very easy to spot.  A simple thing is the rear wheel chain adjuster.

On a works frame, this is on the swinging arm spindle.  Like the B50, but not the same.

They don't even ride the same.

The original frame had some repairs, so our copy has been stregthened in these areas.
