THRUST WASHER,BSA .103-4
A thin thrust washer (57-2680, also known as GB36) used to control end-float in the gearbox.
This is a thrust washer, listed in the catalog as a BSA-spec part carrying the number 57-2680 (also shown under the older GB36 form). Thrust washers like this one take up end-float and keep rotating gearbox components sitting where they should along a shaft, rather than letting them creep side to side.

Our records on this one are thin. It shows up cross-referenced under a gearbox spacer listing with a thickness range of .103 to .104 inches, which lines up with the "BSA .103-4" callout in the description, but beyond that we don't have more detail on file.
Given how little we have to go on, give the shop a call and we'll confirm what it fits and how it's used in your particular gearbox before you order.
