Here are 24 extra samples I have accumulated. Your choice for $8 delivered, or all 24 for $170.

Note the two green samples that have the old Paul-son logo with the big ampersand and no Gulfport, MS address. These don't show up very often.

There are also 8 plain-mold samples which are somewhat scarce.

I have forgotten where the red M chip is from.
Believe it is foreign.
