It is a Mahindra factorty rear remote. My preference would be to convert it since buying a replacement valve body would be about $600.
It detents in all positions, no spring to detent. It makes it a pain to feather the flow because it's rocking on the detent balls when trying to feather it. I tried removing the detent balls and spring but that just makes the lever sit wherever I leave it and it's very possible to bump it to on and it would stay there.
Didn't know if there were internals available that replace the detent balls to make it spring to center. I have two other spring to center rear remotes and when I pulled the cap off to look at those they look completely different.
