This is an inlet valve for the Triumph T20 Cub, listed in the parts books as fitting Cub models from 1959 through 1968. It's a small-bike engine part, and the catalog carries it under 70-3963 with the older WW95059 number showing up as an alternate reference for the same part.

We don't have a lot of extra detail on file for this one beyond the basic catalog listing. If you're rebuilding a Cub head, this is the intake-side valve for that engine family, and it's worth double checking against what's actually in your head before you order, since Cub variants ran across a fair number of years.
Give us a call if you want to confirm this is the right one for your particular Cub before it ships.
