Since its only going to cost me two-cents-worth to throw my hat into the ring, I go with the flower pot (household item) theory. Plus, posting my input is the only way I'll get notified when someone figures out what it really is. Also, I'm curious as to the gap measurement of the two lower prongs? If it was intended for mounting on leather, this gap would have to be fairly close ... say, 1/8 of an inch, or whatever the typical thickness of a leather belt/strap is.
