American Standard Ultra-Mix shower valves/integrated diverter-

I need to replace the diverter and probably the cartridge and handle. Can anyone identify this American Standard model?

Ultra-mix + pressure balancing bath and shower with built-in diverter
Series 1321, I think (if not, 1325, 1351, 1354, or 1355)

Handle 050081-YYY0A
Cartridge 066269-0070A
Pressure Balancing Unit 077171-0070A
Diverter Assembly 077173-0020A

Thanks a lot
