Hi, I have a second hand Eastman A-2 which I was told from the original owner was a house model in a seal horsehide that he purchased new sometime before 2005.The contract number on the tag states: contract No W535 AC 23373 Eastman Leather Clo. If I am correct, Isn`t that a J.A. Dubow mfg. co. contract number? Would it be common for Eastman to use a actual contract number on their house model? Thanks.
