Norton Rocker, Exhaust, R.H. with Ball End
Right-hand exhaust rocker arm with a ball end, from the engine valve gear.
This is a right-hand exhaust rocker arm with a ball end, from the valve gear section of the engine. The catalog record ties it to a single model year, 1975, and doesn't give us more beyond that.

A rocker arm like this pivots on the rocker shaft and transfers motion from the cam follower or pushrod to the valve, opening the exhaust valve on its side of the head. The R.H. designation here refers to which side of the engine it's built for, so it's not a part you'd want to swap with its left-hand counterpart.
We don't have much more detail on this one beyond what's in the description. If you're working on a 1975-era engine and need to confirm this is the right rocker for your head, give the shop a call before you order.
