Pontil bottles like the ones you have shown are more likley to be in the 1860s time period. Nice group of oldies....Love that green large thin lip, food or utility bottle.
sweet finds..........
the large mouth greenie...indeed my favorite, I would think late 1700's on it.
those are awesome finds.....and very good condition overall.
I hope you recovered or are recovering everything you can find from that site.Including MDing the area.Those are some great ...old ....old ....old digs. Congrats....Joe
