Help - Identify Old Amer. Stand. Mixing Valve

first time poster, hoping someone can help me out. I have an old American Standard single lever shower mixing valve that has been leaking like crazy.

I have attached photos since they are worth a 1,000 words -- I'm not a plumber but have renovated houses most of my life so I am a fairly competent jack-of-all-trades, but I'm hoping for a little direction on the steps I need to repair this also. The house was built in 1954 but for some reason I feel like this fixture is older then that - it was a builder's own home and he was the only owner before me.

The handle has a part number of L-1192-2 and the cover plate is 922-1 but I haven't been able to find anything online about them.

Thanks in advance for any help.

 

American Standard

Your post is the only good info I can find. I have the American Standard R 1400 mixing valve and I need a handle for it. I believe it is the same or similar to the B 200. Any info is greatly appreciated.

I have that same B-200 model and need the handle and plate. Do you know of a place to purchase them?

Thanks,

I am a general contractor and need this trim to finish a remodel job that I am doing.

Another first time poster who stumbled onto this thread searching for help trying to find out something about an old American Standard mixing valve that I need to replace/repair, hopefully without destroying the tile in our shower. Any ideas as to what model etc. this is and where I can find out more about it?

Thanks for any and all help!
