What is this rubber profile?

I have a table with no name plate. it's about 25 years old and I was going to put on new rubber when I recovered it. I assumed k66, oops

The curved face is a bit less than 7/8" (21mm)
The flat, glue end is a bit less than 1" (25mm)

That's even smaller than U-23, and close, but smaller than S-38 which I have never heard of.

Any input on profile and place to find it would be greatly appreciated. Thanks





Compared to K66

It's compared to K66.
It's smaller than posted measurements of U-23 as stated in the first post,
and I did post this in Mechanics, I thought I deleted this one
