I'm not good with the little stuff couldn't find a match on VV but it does look similar to those listed.
Wait looking at it for the 20th time it's actually just appart of the eye. (I don't call it an eye lol)but apparently in mint crazy world it is.
Just an FYI @potty dollar 1878 - don't be surprised if you find an unattributed variety from the single-squeeze era. There are a number out there that haven't been attributed yet. I set them aside and wait to see if they ever do. And if I have time, I'll go back and check. I'm pretty sure you know all that though.

Mostly all, if not all the doubling was on the bridge of the nose on these. There was also a lot of cracks coming from the foot of the climber to the right rim.
