Phish, that is a neat looking find. I 'm just going to throw an idea at you here. You say this piece is made of brass, and I'm looking at what appears to be two holes at the top of the piece at either end. I'm wondering if this could possibly be a piece of flag staff that would connect the upper and lower piece of the wooden flag staff. The dimension's along with this piece being made of brass would be a possibility. Was there any markings found on this piece? What is your take? Great find and here's hoping you can get this piece ID'd.
