And surely the face has to be flat to seal? That one looks like some pipes protrude through the flange....

They are clearly (I'd say) home made, welded on the face side and need grinding back for, as glang says, a flat face. Better welded on the other side.     And as TSM says, a 6-1 is a pure race model, that only assists extraction at full revs, 6K+.   But to be useful the primaries must be EXACTLY equal length, and these aren't - the three forward tubes go around the outside of the three backward to the collector, so probably at least an inch longer.

It needs work and probably will never be of any benefit.    Unless you can get for a song, I'd let it go.
