If you want to buy them, email me. Prices shown include shipping. Buy any two and you get the 'R' chip free. We know it was in use with the others but can't pinpoint what it stood for.
The WS is $1.00 on reverse. The others are all same both sides.
If you want to trade, read my lead-off post to see what I am after:
