GEARCHANGE QUADRANT
A gearchange quadrant from the gearbox internals, part of the shift mechanism, cataloged under Triumph part number 57-1673 (also T1673).
The 57-1673 is a gearchange quadrant out of the gearbox internals, listed under the GEARBOX SHAFTS AND GEARS section of the parts book. It's part of the mechanism that translates the movement of the gearchange lever into rotation of the selector mechanism, so this is a wear item worth checking if you're getting vague or slipping shifts.

Older parts books list this one as T1673 - same physical piece, just the legacy letter-prefix numbering Triumph used before they moved to the all-numeric format. If you're working from an early parts list and see that number, it's this part.
Our catalog record ties this one to appearances from 1963 to 1964. That's a narrow window, so if your gearbox is outside that range, check the shape and mounting of your existing quadrant before ordering - gearbox internals changed enough over the years that small differences matter here. Call the shop if you want us to confirm fitment before you buy.
