Pompeian made a somewhat similar pair, though of American Buffalo, stock number 53. I've included a screen-shot of those results, which includes a photo and description of the pieces. NOTICE THAT THEY ARE SMALLER THAN MY BISON.
I find no indication they were designed by Herzel. No breaks in the cladding, nothing dented or mashed. The piece sits flat and stable. 5 1/2 inches tall; 6 3/4 inches long; 2 inches wide. It weighs 2 1/2 pounds. Perfect gift for the collector of things reminiscent of the American West.The item "Antique bison buffalo single bookend Pompeian Bronze clad Paul Herzel exc.
