Does anyone know what exactly this is?

About a month and a half ago I was at a flea market and found this item. The guy there only wanted a dollar for it so I snatched it up but am not exactly sure what it is. At first I thought it was a bow biter for your shoes as I had some Raphael ones as a kid but this seems too big for that. The slots on the back seem too close together for a watch cover. Anyone know what it could be for?
