My observations with the kidney are the laminations of the stator are thinner, maybe a quarter inch or so, that those of the 2nd and 3rd version BMY . Same goes for the rotor. Switch base is the same as a BMY except some Kidney bases have a threaded hole in the bottom side center...to hold the steel cover on. I have never seen a checkered pattern on any BMY lever tip, at least as original. Ring and Loop handle kidney switches appear identical. Nice score on a Hunter Kidney, now you'll need a FWEW kidney to keep it company.
Thanks Kim. I will take a look and see what I have when I return. If I am still scratching my head after I remove the switch cover, I will post some pictures. Guess I was thinking about the Emerson switch lever checkered pattern--it just has a ball on top of the switch lever instead of the black plastic insulated tip.
