I've only ever seen 2 of these, and only 1 for sale. It's rare and would be priced 3X higher but is marked down because it has a couple lip chips. It has an applied double taper top and a robust iron pontiled bottom.

Embossed: STEPPACHER'S / PHILAD // DYOTTVILLE GLASS WORKS / PHILAD.A

Height: 7 3/8" 
Color: deep emerald green

Condition: there are 2 lip chips that span half of the lip of the bottle (see pics). Otherwise, it's structurally perfect with no chips, dings, cracks or bruises. Great collar. Great iron pontiled bottom. It does have some spotty wear, a couple light scratches, and patchy light haze.
