Leo,

It’s neither an ‘A’ or  ‘B’ series. It’s effectively a predecessor to both.

The ‘A’ series engine was first used in the A30, and the Devon/Somerset 1200cc engine was developed into the later ‘B’ series, used widely by BMC and later BL.

Wikipedia refers to it (on the BMC B-Series page) as the “precursor to the B- series” engine or simply the “A40 engine”.

When I took my engine block in for a rebore the guy looked at it and called it a “Somerset” block straight away.
