You mentioned that you bought your Prince from some one from Minnesota at the C.O.C.A meting, was yours one of the two Prince that were for sale at the Chicago show?
I think I may know some one that has or had a Prince I will try to find out if he still has it and what style upper casting he has along with the serial number, I also believe that Don Creekmore from Nation's Attic had a King a wile back, he is a member of this forum but I will drop him an email in case he doesn't follow regularly.
