I am not 100% sure, but I believe this tub plumbing is original to the house which was built in the late 1940's. I cannot find anything that matches it exactly. The tub drain has the remnants of an "American Standard" stamp on it, but I found out that it's not the American Standard Renu faucet that hard way. Can anyone identify this stem? Thread OD is 0.81 inches and the stem is 7/16" 22 spline. The hardware looks very similar to the Renu hardware which is what lead me down the wrong path to start. I'm not seeing anything with a bell shaped end. It has valve seats that are still in the faucet, so no barrel.
Any help is much appreciated!
