Dug this here in Texas a while back...deep teal color, wild rough open pontil, one panel embossed "Boston" right near the base, another panel (partial) embossed OD right near the base. Bottle would have been about 4" in diameter. Anyone know what this was? Very fancy, so I am thinking food of some kind, but the glass is also quite thick. Trash pit dated from 1850's-1870's.
