This is a variety of Seymour PW-VZ that he calls "Square". This one is red with numeral one in a black square. Some call this design "sticks". This is a generic design, not associated with any particular club, but still scarce.

I have only 20 different combinations of color, square color, and numeral in my collection. Rich has many more. I'd like to trade for another combination I don't have, or will send you this one for $10. Other side has tiny nick. Square edges, not serrated.
