That’ll be the 758 for 16J.

Curious that 754 isn’t listed...never noticed that! It was already in play by 1920 in cases stamped “750,” and ran for years after 1926.

Also curious enough, there are two bridge designs stamped 754: spade tips (identical to the 756 except the center bridge) and later round tips—like a fatter version of the 850.
