With a caveat that the C35A originally had the "summer charge" resistor incorporated in its internal wiring whilst the C35M had it externally. The internal resistance wire has often failed and you need to fit an external 3Ω resistor to take its place.
Ian, I think the caveat applies to the CAV DEL dynamo (1928 - 31), which was a four pole machine of a different type. The C35A is identical to the C35M except that:
1) The brush holders are different, hinged arms vs sliding on the later types.
2) I think the front bearing is different. In any case, the casing is different and the C35A requires that the long bolt into the crankcase is removed to allow the dynamo out. The C35M has the casing relieved so that this isn't necessary.
No reason why they cannot be interchanged otherwise, I had several of each type and some mixtures of types when I ran thirties cars and swapped them around incessantly.
