I've managed to break this out into groups that are more-or-less chronological. The first disc was early 1940s, and certainly pre-1943. It had a metal core and this was in turn replaced with another logo, the "banner logo" in about 1948. This new disc had a red and a green variant. The green version is much more common.In abotu 1957 that was replaced for a third time with a modification of the banner logo. The banner was smaller and more centered. I have very few confirmed dates on these. My assumption is that the first was the white one as it has a label. The red and yellow discs bodied that followed had direct-to-disc markings. As this woudl be cheaper, I assume it is a later version and also the last. The Empire State Observatory and the GEM discs are situational and not circulated otherwise. My present assumption is that the black plastic Mutoscope disc is an import, probably British. The disc I cant figure out is the Blue on Blue disc. I'm aware of at least one variant so it had to have been circulated and it's dated to 1948. It may be another import or possibly just a short run. [Contributions are welcome if you know more.]
