I bought this call 8 years ago from the convention. Since then I have lost the business card that came with the call, and I have forgotten the call company's name. It wasn't an expensive call, but it's a turkey killer and I want a back up. Here are two pics of the call, with one being the gentleman's signature.

I would guess it was made by the amish and lasered by Putt Rohm of PA. Bought by this call seller and sold to you. I have an identical call bought at a convention. PM me for the source.
