Farmall F-20- odd ring for spark plugs

Hi,
My Dad bought a 1936 Farmall F-20. The engine is stuck so I removed the plugs to put some penetrating oil in the cylinders. When I removed the plugs, they were smaller Autolite spark plugs. The F-20 usually has large spark plugs, but there is some part that is threaded into the original sized spark plug holes in the cylinder head so the smaller plug will fit. What are they for? Are they hard to find? I've never seen anything like them before. If you can't understand my post, I can take a photo if that would help.

Thanks,
Andy.
