"I would bet one of them rectangle or diamond is the real deal for this club as many clubs I see have 2,3,4 different molds."

I will take that bet.
I have 11 different hub ID's, 4 different Taylor, 3 different Jones, 2 different Hunts, 2 different plain molds, and 1 Treyball, total 23 for BC initials, no two for the same ID.
