CAM RING K2F ANTICLK MANU
Anticlockwise manual-advance cam ring for a Lucas K2F magneto.
This is a cam ring for a Lucas K2F magneto, the anticlockwise manual-advance version. The cam ring is the piece inside the magneto that rides against the contact breaker heel to open and close the points at the right moment, which is what times the spark. On a manual-advance magneto the ring gets moved by the rider's advance/retard control rather than by an automatic mechanism, so getting the correct rotation and the correct ring for your magneto matters.

The part also shows up under number 308 in older catalogs, which is worth checking against if you're working from an early parts list or an original magneto that hasn't had its numbers cross-referenced yet.
We don't have much more detail on this one beyond what's in the description. If you're not certain your magneto is a K2F with anticlockwise manual timing, give us a call before ordering so we can confirm what's actually on your bike.
