Other than the dodgy trailer light for a tail light it looks pretty original. It really only needs detailing and a spruce up. The patina, including the tail light, just gives well deserved character.
I'm not a Monty expert (Ross would be a better reference he's had Monties longer and has a H6) but fire away here or by PM.
Congrats Rodge, you getting quite a diverse and desirable collection.
