[Gearbox number GP]

Indeed, that stamping doesn't look factory. Difficult to explain, but I expect it is a recon at some point.

Looks like  4 cylinder gearbox, is the gearbox rear flange round or squarish? That is a giveaway (squarish is a 3 synchro, round 4 synchro) thogh all od usnits areround outputs. Other tell-tale is bolt head size, 1/2 or 9/16? And what car of course...though that is not a terribly reliable indicator.

The car is a 65 herald 1200, with original engine.  Bolts are 1/2 inch. I'll check the rear flange later.  Thanks for your help

My gearbox number starts with GP, but I can't find any reference to this prefix.  Can anyone help please.
