Trying to find a part like a Kipp handle

[DReimer]

I'm trying to find something that operates like a kipp handle, but isn't.

I have a cylindrical part that I would like to be able to index around its axis using a kipp handle concept: pull out to rotate, spring return to lock in place.

Does anyone know if I can buy an assembly of the mating serrated parts with a spring, but without the handle?

Thanks in advance,
Dean
