All I've been able to find is that it may have been sold through the "Ace Hardware" chain of stores. I would imagine that they were produced for Ace Hardware by some established sporting goods company. Something about the font of the stampings says "Spalding" to me, but that is just a guess. Anybody know anything about these?
The first picture is the actual mitt I worked on. The second two are pictures of a mitt I found for sale on the internet.
