here is a nice olive green 1850s iron pontil Whiskey bottle from philadelphia.  this bottle is base embossed "DYOTTVILLE GLASS WORKS PHILADA" and has PATENT embossed on the shoulder.  this bottle has an nice amount of bubbles in the glass and a well defined pontil scar that retains a healthy amount of graphite.  there is some roughness on the collar in one spot (see pics) and some surface scratches but otherwise is in excellent shape! this bottle is roughly 11 1/2'' tall. feel free to message with any questions!
