My Census List shows various Moris Commercial Cars Contracts that might relate: 'Carrier Predictor AA no 3 SPM' to V3957 that included 'Carrier 40 mm SPM', plus V672 'Carrier AA Pred 40 mm Mk III', and V4497, 'Carrier Predictor AA no 3 SPM' and 'Carrier Predictor 40 mm SPM'. All had 'S' prefixes.

Note the C8/P has a very similar chassis to the normal and Airportable 17-pounder. Were there surplus MCC Predictors by the end of 1943, hence C8/P trucks were able to be converted by MCC in Birmingham as well as the C8/AG and A/T Mk III?

Carrier Predictor AA no 3 SPM = truck carrying the Kerrison Predictor (no 3 Predictor).

Carrier 40 mm SPM = truck carrying the Bofors gun.

Carrier AA Pred 40 mm Mk III and Carrier Predictor 40 mm SPM seems to be the same thing only that different persons have written the orders different.

Could SPM mean "Self Propelled Morris"?
