I’ve owned this belt for a couple of decades. It’s a large harness buckle with a harness leather belt. The belt has a number of various stamps used by Heiser for retailers who sold Heiser’s products. A few are saddlers, half of the stamps can be found on holsters or sheaths. I have items with 8 of the different stamps.
I’m guessing that this was made up for a visiting retail buyer, company bigwig or somebody they wanted to add to their stable. I’ve never seen another, I doubt it’s the only one but it’s the only one I’ve ever seen or heard of. The White & Davis, Reising and Browning Bros. stamps were used before WW II, I would think the Randall and Keyston Bros. stamps were used up into the 1960’s.
Note the Powder River stamp on the holster was applied over the common oval Heiser stamp.
