There is no difference between the skimmed P11, P11A hub and the ribbed Ranger 750 hub, front or rear, if that is what you are asking. There are other AMC ribbed rear hubs for the CS and CSR models (pre-64, Norton hubs used from '64 on) and the lightweights. I'm not a Matchless guru, so I don't know how they differ. The key here is P11' s used Matchless "interim" hubs which were only used on AMC (non-P11) bikes in 1963, the switch to Norton hubs for the Matchless/AJS machines being 1964.

The "interim hub" statement applies to the front wheel only. The rear wheel is of older design, dating back to 1956 and the introduction of the short stroke G80CS.

P11, P11A, and Ranger 750 all use the rear wheel design with the sprocket integral to the brake drum (like Norton). As I understand it, the detachable sprocket hubs are found on the earlier "lightweight" singles.

The detachable sprocket hubs are found on 1960-62 QD (Quick detachable) hubs as fitted to DeLuxe models, and on the 1963 "interim" rear hub. The latter is a development of the former using a ball bearing in the hub and a roller bearing in the sprocket/brake drum. 5 extended nuts need to be unfitted in addition to the spindle nut and the spindle itself. The 1960-62 QD hub had 5 driving pegs which connected to the hub via rubber sleeves in the hub's drive side (not a great design IMHO because pegs are rather short, also a preamble to Norton's infamous 3 vane cush drive introduced for 1971), the 1963 hub/brake drum connection is "hard" without sleeves but also stout, and thus similar to the 1964 Norton rear wheel design. The hub is not really a "quick detachable" hub though.

Pic shows 1963 interim hub. No grommets were offered according to the spares list. The hub has 5 fins.
