These are non PMA’ float fittings made for the piper line of tube and cloth aircraft. They do not require welding and therefore, are the bolt on variety. No damage to the tubes at all.
I believe they fit all the rag wing series. They also would work for other aircraft that are welded tube fuselages. These are usually fit with floats such as the Edo 2000
Can be smaller in displacement as well.
