Identify this Delta shower valve | Terry Love Plumbing Advice & Remodel DIY & Professional Forum

I was wondering, could you identify this Delta shower valve? I am at my grandparents house. There are two of these valves paired with the Delta pull-down diverter spouts and Delta arms, one with a 5.5 inch Moen Engage with Magnetix showerhead and the other with a Moen Adler showerhead.
