Replacement handle for a PVC ball valve

I’m trying to replace a handle for the ball valve opening and closing the drain line(see pic - only for demo purposes, its a generic image). Te idea is to avoid the plumbing job replacing the whole valve. Can’t figure out who made that valve. The remaining part of the handle (see pic) shows something like JJ, but nobody knows what it is, at least at my pool store. What I see as currrently sold would not fit the stem (see the picture). The handle is screwd on to the stem. Any help would be greatly appreciated! Thanks, Paul

Hello Paul - We have a handle tool that fits most of the common ball valves. The part number is 6650-30.
