Do you know what this engine is?



Thank you for looking and good luck guessing

Looks like an Alta engine, probably for a 1½ or 2 litre supercharged single seater c 1938

Correct, it is an Alta engine, and it is from a single seater, however the other details you have given are not correct.

Here it is from a different angle.

Ah, the "supercharger" was not part of it!
As fitted to a Connaught B type then: as it has a starter ring on the flywheel I guess it's B5

You got it, well done, it's a 2.5 litre Alta as used in a Connaught B Type.
