WTB: Lemco or RS silver mica or ceramic caps

[shakti]

I'm looking for some parts for Hiwatt and "M" builds. Trying to hunt down some NOS Lemco or RS (Radio Spares) silver mica or ceramic caps.

Particularly looking for:

47 pF
220 pF
250 pF
270 pF
470 pF
500 pF
560 pF

If anyone has any to spare, I'd love to buy some, or we may be able to work out a trade.
