What type of shower valve is this? American Standard Ceramix

[Sharpie]

Trying to identify what brand's shower valve is this?

This bathroom was gut rehabed in 1999. Bath overflow plate indicates "Gerber."

Any advice appreciated!

It could be american standard ceramix. Guaranteed for 50 years but taken off the market after ten.

Interesting. Thank you for the input. My lever handles appear to be American Standard's "Hampton".
