I have received 10 of the 12 shotguns so far. There are some great chips in there. Since I'm not sure if the owners knew the ID's or not, I am going to post them here for all to enjoy.

3M (linked) HARP mold, Shipped to 3 M Novelty Co., Benld, IL 1946

(an arrow through a circle & with a radial circle of vertical lines) PLAIN mold, Used at Chief Satiacum's illegal American Indian Casino, Tacoma, WA 1970's

Three different SCROWN chips used at the Cottage Club & Card Room, Hanford, CA 1958 to Present, "EV"; "FP"; "EEEE" (in a shamrock)

WL (Walter Lafargue) LGSQUR mold, 4700 chips ordered for Jefferson Parish, New Orleans area, LA between 1962 & 1970

The chips that I sent out are unknown to me. If anyone knows, please LMK.
