Had a nice visit with Mike Hughes, He has the best records of HDX Plastic that I know of as well as blowing my mind with WFC discs, so many color combinations, I had no idea! You learn something everyday & with each new person I meet I see new plastic, new & old I have never seen before, like the minis below.
Wham-o # 3 mold, interesting disc the only # 3 molds I have are with this stamp. I have a second # 3 on a blank yellow, different from this disc the yellow has Burry script on the underside in addition to the usual script. The # 3 on the underside is also different in size. Otherwise the disc looks the same in size!
