Norton Cup, Primary
A Norton front brake master cylinder cup, listed under part number 06-1942, with a 1975 catalog appearance.
This is a Norton part number, 06-1942, listed in the catalog under a brief description of "Cup, Primary." The catalog places it among the Handlebars and Front Brake Master Cylinder and Hose Group figures, which points to it being a small cup-type component somewhere in the front brake master cylinder assembly rather than anything to do with a primary chaincase.

Our record on this one is thin - just the single line entry and the one catalog appearance, tied to 1975. There's no further detail in our files on dimensions, material, or exact placement within the master cylinder.
If you're trying to match this up with a rebuild kit or a specific master cylinder assembly, give the shop a call and we'll confirm fitment before you order.
