Can't speak for anywhere but Australia, but I have seen ex-military 
variable caps on Yahoo auctions over here.  But you're right, neither 
Farnell nor RS have them listed (I haven't tracked down a Digikey Australia 
yet).

Old wireless sets should be plentiful in junk shops, so that may be the answer.

This does raise the question: how do people build radios now if you can't 
get variable capacitors? (Apart from trimmers.)  I'm sure that they don't 
use variable inductors and I didn't think that RC oscillators were suitable 
for high frequencies; forgive me for being out of date...

Cheers
