Well, there are a few antique clubs marked with a script stamp, so there might as well be an antique ball marked with its name in script. And there is! The six-pole bramble pattern rubber-core ball offered here, not listed in any of the golf ball reference books, is marked in raised script "Capon" on one pole and "Heaton" on the other. Not only is this possibly the only the second of these known, it's in drop-dead-gorgeous mint condition. Wow!
This ball is middle row left in the group image that accompanies this lot.
