Here are the photos so far, per Plutek's request:

I might pull the rotor off completely once I've put penetrating oil on
all the rusty bits - then I'll get a close-up of the entire rotor.

I'm pretty sure that the way that the line is marked would mean that the
tone would run as a sweep between the lower and upper frequencies - and
25 times per second at that. Should be an interesting noise -
especially once it's been fed into a synth ;-)

That I can't tell as I haven't powered it yet. Think I might replace
the capacitor first - don't know what will happen if I energise a 40
year old capacitor, but don't want my office full of shrapnel.

Rotor spins very freely so I'd guess that it would get to full speed
quite quickly.

Cheers
