Oil control ring
A Triumph oil control ring for the piston, cataloged 1964-1966 under 70-3692 (formerly E3692).
This is a Triumph oil control ring, listed in the catalog under 70-3692 with the earlier E3692 form also on file. It shows up in the crankshaft and connecting rods section of the parts books, so it's a piston ring rather than anything crank-side despite where the figure groups it - oil control rings live in the piston, scraping excess oil back down into the sump so it doesn't get pulled up into the combustion chamber.

Our records show this one appearing across catalog entries from 1964 through 1966. We don't have a breakdown of which specific models pulled this ring in those years, so if you're matching up a rebuild, check your bore size and ring specs against what's actually in your engine before you order.
If you're doing a full ring set, it's worth pulling all the rings and having someone measure bore wear at the same time rather than replacing this one in isolation.
