Odd Request: War of 1812 Cannon

Hello, I'm posting this as a feeler for a local institution. Living here in the Buffalo, NY area, we have a lot of history with that war, and a local radio host is trying to locate a period cannon to put on display. That's all I know, figured this might be a good place to start.
Any interested parties can PM me here and I can supply the contact info. Thanks!

From what I've learned, this local radio host has already spoken with both and wasn't able to get anywhere with them. The goal is not to purchase, but work out some kind of loan arrangement, if possible. Thanks for the info, though.

I will. Thanks for the leads.
