My collection of other ones all fit in a case 12 x 18 ", so I may have to get a larger case.

I enjoyed reading the patents, which actually are not just the stamped one, but two patents cover this particular model US2316500, US2397916. The large weight was an option in the 1946 patent, which the inventor notes could be used as a hammer or fish billy, and optionally detached when packing for a trip and substituted with a rock in the field. I can really see this old fisher/trapper out in the field depending on this device optimized for multiple uses.

If you run across any of these, particularly the Hardy version, I would be interested in them.
