I can't remember who sent me this chip, so hope he is reading the board.
As you can see it was probably used on a military base. APO San Francisco, is likely it was used on one of the Pacific Islands. I have all 4 chips, and the chipper I got them from has more.

Anyone know how to search the web for SFC Thomas Harris. Would have to be retired now (If alive) as chips was shipped in 1959. His service number is on the Mason card. I would like to know exactly where they were used.
