Status: offline 		Could someone tell me the approximate age of this engine?
Is it a MkI, a MkII, a MkIII or a MkIIIA... or something else all together?

It is completely different from the Irvine .20 "pylon" engines we use in racing over here.
It is indeed an "ABC" construction, but unlike any I have ever seen: the sleeve appears to be cast...? And it has multiple bridges in the ports, like the sleeve was originally intended to be used with a Dykes ringed piston or something. This makes me think it is rather old... but on the other hand it has a plastic rear cover...?

Anyway, I'll attach some pics... maybe someone can make something of the part numbers....
