This is the rear wheel spindle spacer for Triumph swing-arm twins and triples, part number 37-1024, also cataloged as W1024.

It shows up in the parts books under the REAR WHEEL figure across a long production run, from 1960 through 1974, so it has seen service across a good number of rear wheel builds over the years. If you're rebuilding a rear hub or freeing up a stuck axle, this is a small piece that's easy to lose track of or mix up with a similar-looking washer, so keep it identified when you pull the wheel apart.
Given how long this number ran in the books, it's worth having on hand any time you're doing rear wheel or brake plate work rather than trying to reuse a tired or mangled original.
