My 74 mk2a is original as far as I know, however the engine number and frame numbers don’t match, the gearbox number is the same as the engine

engine 3083**
Gearbox 3083**

frame 850 102807

every nut and bolt I’ve removed recently appear to have been there since day one.

850 F102807 ?

That's normal.
The certification plate attached to the headstock (assuming it is still there) would normally be stamped to match the engine and gearbox.

The red plate is solely marked 09 73 and the space for other details is blank.

thanks for your reply.

There was one on Fleabay recently and it appears that someone had stamped the ID plate on the headstock with the frame number rather than engine and gearbox number.

Built on a Friday and someone forgot to stamp the engine number in the box on the plate possibly, as it had the frame makers own stamp the licensing authorities had a number so ignored the blank box. My MK2a is 11/73 and 31041* so yours is in the right sequence.
