Id this valve please?

I'm having a heck of a time identifying the manufacturer. Please help me...
It's not that old a valve, two years at the most.

Nothing jumps to mind, although the on-board diverter does limit choices. Could you post a pic of the handles? That may do it. Next step would be disassemble and post pic of innards. But someone probalby will recognize handles.

Also the trim plate that fits against the wall.

I wish I could...My plumber installed them, told me they were Moen. But, I can't find anything that lines up with them.

My plumber has since disappeared and i have five of these installed in my home. I don't have anything else to go on. But if necessary, I will remove the cartridge? ??

I really need to know, my remodel is 95% complete, and I really would hate to rip open walls...
Thanks again in advance..

You do have one advantage, assuming they work, you have in-line shutoff valves going into your shower valve so if you do take it apart, you shouldn't need to shut the water off to the whole house. You might want to do that anyways in case they don't work! Then check them. Turn the screw so it is perpendicular to the pipe to close, align them along the pipe to open.
