Nother very nice go with for the insulator and bottle collector. This is an FM & Co ink in a very nice bubbly green. This guy is quite old, has the penholder on the rear side of the ink which is inset into the bottle itself, plus there is a small piece of black junk embedded into the glass in the thinwall to the rear side. Very cool embossing on this! There is a short sword embossed on the front right next to the F M & Co embossing. Never seen an embossing like this one before. VVNM, the usually tiny nips around bottle opening but no other damage to this delicate bottle. First mail to me... $40 shipped in USA/CANADA, other countries I will assist with ship costs.
