Jack Scruby was one of the pioneers of American wargaming providing a miniatures across a wide range of scales and historical periods. Scruby used RTV molds made of silicon rubber which allowed some level of undercutting on figure sculpts, something not possible using molds made of metal. He offered a well printed catalog and sold figures for a nominal price either by mail or through his store.
Additionally, he wrote a number of rules sets, edited and published several magazines on miniatures gaming, organized a club, as well as one of the first miniatures wargaming conventions ever held.
The figures seem relatively uncommon on E-bay and are probably interesting as much for the collector as the gamer. The figures I have seen are reasonably well proportioned with a toy-like appearance. There is little surface detail and just the simple outlines of face, hands, and equipment. Surface detail is lacking. Nevertheless, figures are reasonably proportioned. There is no sense of gnomishness.
I imagine that at the prices he sold these at, there are a lot out there, likely tucked away in boxes. They are one of the oldest wargaming figure sets made in the US.
