Good news, Betty fans. At long last, the coveted sink handles have been put in place. There's a bit of a story to it, making what is a small thing non-trivial.
You may recall that I decided the sink itself is OK, and kinda unique in being a "ledge back" design. My only real complaint was that the chrome on the fixtures had stripped off significantly.
When I say, "kinda unique", I am not kidding. In my earlier quests for sinks, I only found a couple of models remotely like this. Fixtures were even harder to find. This whole notion of having the handles mounted on the front of the ledge seems to have been a quaint mid-century one, one that has fallen by the wayside.
I asked my super where I might find parts, and he directed me to New York Replacement Parts Corp. "If they can't get it, no one can." So I went (twice, as it happens, but only bc I didn't realize the part was adjustable).
I showed the clerk a photo of my sink. "American Standard," he said, almost immediately. I ended up replacing the entire set of pipes and handles. Also, I was limited to one design. American Standard apparently makes just the one set.
I found a plumber to come install the next day, and now I've got some better-looking handles.
Now, they're not great. They're not an "iron cross" and don't have enameled labels, both of which I would have liked. They're small. However, they're clean, a bit shiny, and apparently stainless steel, which ought to keep clean easily. They're a darn sight better than the flaking chrome and faded colors of the last set. So, I'm happier with these.
Coming soon: the main show. The larger bathroom model should be done in a week or so.
