I picked this up earlier this week as a decent filler for my type set. It was covered in gunk, residue, and all sorts of things. After a few acetone baths, I'm left scratching my head as to what variety it is, which is why I am requesting your input and brainstorming power. Unfortunately, my laptop is being very uncooperative at the moment, but I managed to get some scope pictures uploaded, cropped, and hosted on imgur. Here's some screenshot pics of what I uploaded there, but with far lower resolution. The full resolution pics of these, and additional photos along with a short video are here on this imgur link: https://imgur.com/a/rKgv5jJ I am referencing this site: https://www.seateddimevarieties.com/pictorial/1871.htm for trying to figure out the variety, but it's not exactly matching up with any. If you can offer any help or opinions, it would be greatly appreciated! And yeah, it's still got a fair amount of crud stuck on it, even after a few long baths. Any tips on removing it, or just let it be? Thanks!!
