[ForSale-Swap] Drake 4 line crystals

[Michael Smith]

Hello to the group,

I would like to find a 21.1 MHz crystal for my B line. I have several SW BC
rocks to trade or would buy the 21.1 if someone has one. I would trade two SWBC
for one 21.1.

I would also like to find a 40.1 crystal.

Thanks,
Michael Smith
