Need help Identifying a mid- century piece.

Hey Cube Nation! I am looking for a specific Double old-fashioned glass for a show and I've spent 3 days on Google I can't find it anywhere. I've tried "optic dot" "bubble glass" "Hazel Atlas brand" and every combo of mid-century, mod, glass, rocks, double old fashioned you can think of". I have a similar object, and I am wondering if anyone knows who the maker is or what brand it is, so I can narrow my search. Photo attached below. Side project, if I cant find the glass, I may want to have someone cast it, anyone good with clear resin? Thanks for the help! Sean
