You have to much time on your hands.
I dont want to sign up to another fourm so you can pass info on if you like.

This is a very old push pull. I doubt seriously if you would be able to move it after so many years but you can try. Just be prepared to replace the insides when you break off the handle.
Looks like a Sta-rite WC212 push pull valve. Though they operate differently now.

I just build them, dont fix them often, so if anybody else has something to offer feel free to chime in.
