Head and barrel look to be a Goldstar. But they may be Goldie bits on a cooking bottom end. I suspect it's a bitsa.

Check out the ADV link - it's an XB33 bottom end with an early Goldstar top end....B33 cams,B31 frame.

Yith. Bitsa. Still, could be the basis of a nice bike. I never had anything against mongrels.

Front wheel's later than the frame. Wonder what the gearbox is. Just might be a wide ratio scrambles box ? Or a close ratio?

Was interested wether it was a bitsa or not,sounds like it is eh.Definitly the basis for a nice bike methinks.

A Goldstar top end is a forever unfulfilled dream for a B31/B33 owner....but not much good without the cams to take advantage of the bigger ports and valves.You could certainly make a nice bike out of it.

I think the plunger frame came out in 1950,and the swingarm in 1954 - so somewhere in that range.An anorac could pinpoint it to the names and family members of the assembly workers....but in this day and age very little is original.
