Anorak time!
I have the AC Delco information book from 1962 which lists all the original pump numbers and the replacement "factory exchange "unit. For example the 1932 Seven was fitted with 856728(M) with the FX version 7950221 - this replacement had a priming lever fitted! This was not fitted on any of the original pumps, but on all the FX ones! The FX unit fitted all models of Seven up to 1939 and was interchangeable with 856728 (M), 856841(M), 856964(T) and 7950221(U). The book does not show lever part numbers only filter gauzes, Filter gaskets (nothing for "M"!)
The side valve Reliant Regal Mk2 & 5cwt vans of 1960/61 used a different pump (7950567YD) which was unique to those Reliants. Whether it would work on an A7 camshaft....who knows? Nothing earlier than 1961 is listed under Reliant.
