was 2-stroke (eg Commer "Knocker") or 4-stroke.

Certainly the had cranked static diesels of the era, had a lever to
release the compression, so the could be cranked over. You moved the
lever, cranked up to speed then released the lever to hopefully have it
fire up. Possibly lorries had a similar device too, to allow the starter
to crank the engine over. Called a 'valve lifter' I think (?)..

Correct. Also found on soem motorcycles (mainly big single cylinder
jobbies) to make kick starting easier.

I remember a friend of mine had a 500cc 'single' that seemed to do about
5 rpm!
