So I have been staring at this for hours. and hours. Using 3 diff types of equipment.
I have 2 ideas of what the image is but I'll wait and see if anyone knows. I have googled, I have tried several reddit forums, so I thought I'd try here.
This ring is "likely" from the 60s. I think I read that imgur is ok. If not please do let me know.https://imgur.com/a/KyDgLBd
so my question is, what is the mark to the left of the 750?
Thank you all.
