Vintage Sink Strainer Twist Lock Basket Stainless Threaded Stem 3 5/8"

Vintage Sink Strainer Twist Lock Basket Stainless Threaded Stem 3 5/8" This is the original twist lock sink strainer that came with my Kohler sink 25 years ago. The sink has recently been replaced but this wonderful high quality stainless strainer doesn't fit the new sink. Top Diameter: About 3 5/8" Total Height: 3.25" I don't see any brand name on it but it does appear to be stainless steel. You can see from the photos how nicely it has held up all these years. You can probably also see what looks like some rust on the stem part beneath the basket. The twist part that you turn might be brass that looks like tarnish. I was told that it might be a brand called EZ-Flow - but I have no way to know for sure since I don't see any markings. (If they are there, they are probably too small for me to see.) For that reason, I'm listing it as Unbranded. Please do not hesitate to contact me if you have any questions. Thanks for Looking!
