Certainly no offense taken at all. I should have included all that information to begin with. Right now I'm seeing similar, but not identical fixtures from ROHL. It almost seems to be a shower/tub diverter with pressure valve, being used only for the pressure valve, with the tub output plugged, and some sort of hot/cold output mounted on top. There is a separate diverter in place. My luck to get someone's modification in my shower!! The search continues.
