I'm going to be selling the clamp shown in the pics that I've posted with some other excerss hardware in the near future. From what I've researched, read, and seen on-line, I believe that this particular clamp was made by the Rogers Drum Company for use with its Swiv-O-Matic bass drum pedals. However, I can't seem to find any identifiable markings on the piece. Did the Rogers Drum Company actually stamp their I.D. on their clamps? If not, is there any way I can determine FOR CERTAIN whether this particular clamp is, indeed, a Rogers' product?

I simply want to make certain that I'm not providing any type of inaccurate information to a prospective buyer.

As usual, thanks in advance for your input!
