Overflow tube under sink that seems to no longer exist

[johnny steele]

Can't find a replacement for my overflow tube that is attached to the bottom of my bathroom sink. The plastic were the hole for the p trap looks as if it is no longer the original shape, plastic has splintered off so no known washer will get a good fit. I wanted to replace the tube but all the plumbing supply stores tell me there is no replacement. Any suggestions would be appreciated. Of course, I don't know the make of the sink.

That part is SPECIFIC to that make AND model sink, so without a manufacturer, you are out of luck unless you get real lucky and someone recognizes it. That was a fairly common way to put an overflow on a "cast in place" sink so they did not have to try and make a passage inside the mold.
