Talking with Kohler wasn't any help, both Man's Lav and Lady's Lav are discontinued and faucet sets no longer available. The CS rep wanted a part number but he should have access to 70's info better than me. They all used the same cw close valvets and the only difference in part numbers was for handle type and finish. I told him Flair in gold plate with amber acrylic handles but he still wanted part a part number even after saying he couldn't help.
I guess I am just stuck. I would insist upon free replacements but Kohler doesn't seem to have anything in a swing spout (they are all too tall) that would work and I am not sure if fixed spout would serve very well in the Lady's Lav.
It's all a bit depressing this was all high end when I purchased it in the 70s, 2 ea Lady's Lavs, 1 ea Fiberglass tub/shower with fixtures, 1 ea soak tub (American Standard) with Kohler wall mount faucet set and 2 ea Rochelle Closets all with gold plated finish on spouts, handles and etc. It's too bad Kohler didn't have the savvy to make a direct fit replacement cartridge with ceramic disk or whatever that wouldn't drip.
