Trying to identify make of this valve which came with my friends new home. I suspect its one the home depot specials but have had no luck so far in my searches. The rough valve body in wall is stamped on top-side with GOBO ASE1016 or AS51016. On back of trim plate is a sticker with # 12085. The diverter function is integrated into the valve body. Thought it was an Innova brand by shape of tub spout but after speaking with them its not. They're diverter is a push-button type, not lever. It looks like real heavy-duty brass, I suspected maybe Pegasas but couldn't turn up anything of the like. Any ideas??

Btw, reason is I need to replace the diverter part, o-ring washer is leaking inside.
