This is a super example of a late Civil War period Philly squat. It has an applied double taper top, nice mold impression, and smoth-based.
Embossed: W. FULTON / PHILA // F (large open block letter)
Color: light blue-green (nice color variant)
Condition: near mint - structurally perfect with no dings, chips, cracks. It's pretty clean for a non-tumbled bottle, just trace wear.
Reference Number: SH313
