Which tannery does this?

Bought some deer capes from a guy the other day and would really like to know where they were tanned, it was an excellent tan and the ears were very strong when I was taking the cartiledge out. The guy couldn't remember who did it but they had a red numbered tag, about the size of a quarter, zip tied to the ear butt. He though it was either wild life gallery, east coast or keystone. I had a hide that was supposed to have been tanned by east coast but it looked and felt alot different. It's a wet tan but is leather like a dry tan makes. Thanks for any help and hope that all makes sense!
