In 1992 or so, a customer requested a one of a kind item from the famed Gorham Manufacturing Company - the preeminent American manufacturer of silver and bronze foundry. He wanted a copy of Augusta National's famed Bobby Jones sundial. But not in bronze - he wanted it cast in Sterling Silver. After initially refusing the request (Gorham didn't make silver statues of this size), VP of Gorham Fred Roy took up the case and oversaw the casting. Though the statue is stamped "Gorham Silver" on the base, it is most likely closer to pure silver, as casting would require a richer mix. This would also account for the weight of the piece (over 4 pounds), ad the fact that it hardly tarnishes.
The resulting one-of-a-kind Bobby Jones sundial made of Sterling Silver is a true work of art.
