Dave I can't remember if I have asked you this question before so I appologize if this is a reapeat.
Two years ago Terry Calhoun was at In Flight sports when they recieved a shippment of discs. As the box was being sorted out the employee said "hey theses Valks are double stamped" Terry looked at the 4 misprints which were stamped once as a 150gm Dragon then again as a CE Valk. All of them are 174gms and look and fel like heavy Dragon plastic. I Traded Terry for one of these discs. What do I have?
