I have had luck with UG rated vintage Leica lenses. Old Leica lenses tend to be fogged due to the organic factory lube but most of the time they can be cleaned without destroying the coating. My one time gamble with an as is CL didn’t work out.
I got an as is N90s with battery grip and it would focus hunt and not lock on focus. I cleaned the very dirty mirror and it worked perfectly. It was a whopping 18.00 shipping included.
