BTW- There is only one vintage 7mm crown that I would consider spending the money on, and that's the non-Triplock version that came on the original early models prior to release of the Triplock system. If we're talking vintage Triplock vs. modern, there just simply isn't enough difference to me to justify any extra cost, as they are virtually the same in terms of size, function, etc. Only difference is the shape of the coronet of the stamping. Going back to the non-Triplock crown, that particular crown would be incorrect on a 6263, as they are all 'Oyster' signed with screw down pushers, etc. A 6239/40/41/62 with the pump pushers would be a different story.
