Rings, Piston 39-20058
Same part # for KE7,KF7 & KG7
Have you tried Fergusson Poole?
If all else fails Otto Gas Engine (requires you to measure pistons to get correct size if I recall)
Good Luck
It is easier to find what you are looking for if you know what you are looking for.
Always a good idea to start with part name and part #.
Anything that can be misunderstood will be misunderstood.
