Job to say from that angle.

Looks like slimline crankcase from photo of the left hand side could be 36/37A type but would need to see right hand side as could be 11E type

This is the flywheel, looks a bit odd too - can't find similar on web. lots more holes than normal? looks more crudely machined than you might expect too

I don't think it is a 10E. More like a 1H; 224cc, or 2H, 246cc. Is it a 66mm bore, Mark, or 63mm? They share much with the twin engines, and that appears to be a 2T-type flywheel. If so, it would explain the non-standard engine plates.

Mark The engine plates are not Greeves design, I have drawings for both the single (9E 32A etc) and the twins (2 3 & 4T) and neither resemble the plates in your bike. The cylinder is definitely not 1H or 2H and neither is the flywheel side crankcase half as the upper dowel pin is not in same position, also the small rectangular hole in casting just behind the cylinder is for the 9E/32A type 2 pin lighting socket. The 1H & 2H also have wider engine mountings.
I would agree with Ian though that the flywheel looks the same as the 1H / 2T type. So I think the engine is basically a 9E /10E
It beggars the question as to why someone would make bespoke engine plates when Greeves ones would do the job!
Have you a side on pic of the whole bike Mark, whats the frame number?

It makes you wonder if some creative soul built an engine from disparate Villiers parts?
