Running an old Queen – help?

hi, a friend is building together a rig to ground run an old queen (motor that is!) he brought at an auction but needs a few bits which may be knocking around someones shed. at the moment he’s after one of the electric mk4 rpm indicators and the thermocouples (right word?) for the cylinder head temperature gauge, smiths type i think but not sure which type exactly.

please pm me if you have any thoughts as to where some may be available?
