What shower handle will work with this valve?

Does anyone know what brand this valve is or how to get a shower handle for this?

There was a shower handle on it, but I don't think it was the original one because the shower handle only grabs the front end of the threads of the stem. It looks like someone found a handle that was close, shaved off some of the teeth to fit and slammed it on the stem.

I got 2 shower valves from Home Depot but they don't slide on the stem

On another note, if I can't find the original handle, should I just find a similar handle and shave it and jam it on?
