My best guess: The player endorsement is Bill Killefer. Goldsmith produced Killefer-endorsed mitts as early as 1924 and then right up through the mid-to-late 30's. His mitts didn't appear in their catalogs for a few years after that, then, surprisingly, popped up again in 1941 and that appears to be the last year they were offered.
The earlier models had a model number of "WC", while the later ones carried the model number "BK".
Just to show you how different the world of player endorsements was in those days, Killefer was a fairly non-descript catcher between 1909 and 1921, then a manager for the Cubs (1921-1925) and the Browns (1930-1933), where his teams amassed a .457 winning percentage and never finished better than fourth place.
How that warranted a personal glove endorsement is hard to tell. But it wasn't uncommon to find obscure player endorsements in those days, when the sporting goods industry was in it's infancy and many of their products were marketed on a regional, rather than national, basis.
