ID a Shower mixing valve?

[logdy]

I can't find any markings on the mixing valve.. I'm trying to get a new trim kit The house was built in 93.. The pic is attached.. Thanks for any help on my quest... I first thought it might be a Cifal valve

Any chance you could remove the stem and snap a picture of it? Hard to tell anything from head on, especially when it is still in the wall.
