I'm looking for some obscure, small parts for a 1970s Tama King Beat pedal that I've just acquired.

I need the "eyelet" bolt and accompanying nut that secure the beater shaft into the pedal.

I also need one of the knurled bolts that act as spurs and the accompanying spring, though that's not quite so important.

Anyone know who might have these?

(PS I'm in SW Wales, UK)
