If it weren't opaque green I would suspect Pairpoint. The overall shape etc., is like a number of their items I have in different colors and glass types. Since I'm only interested in some of their glass; I haven't done a lot of research on everything and color they have made over the years.
If you don't know you should: Pairpoint has had a few lives as a glass company, open, closed, open, closed, open.... The original took over Mt. Washington Glass and then Gunderson Pairpoint did their own thing plus some glass the original was doing and then Bryden Pairpoint took over and they too did their own thing, plus some glass like the two before. Pairpoint is now owned and operated by someone else, but I can't recall who.
I am told that the original Pairpoint and Gunderson both finely finished their wares, while Bryden sometimes left rough or bumpy feeling pontil scars on some of their lines, which appears to be their opaque type glass, since all of the transparent 34% lead glass I own or have have seen has well ground and polished pontils.
