Hello Marcus,
I would say that the MOV was introduced around 1928, the M type is earlier.
From all the carburettor information on Austin's that I have the giveaway is a Brooklands had a jet marked just by the size. Whereas the Ulster is size x 41. The Ulster jet will not fit an earlier carburettor and vice versa.
The M type jet and carrier were also fitted to the D type which is more likely used on the Brooklands.
Best wishes,
Robert.
