The pontil on this looks British, otherwise I don't know much about it. It's in gem condition. The bottle itself is a 3-piece mold, with an applied seal on the shoulder. The top is also hand applied. Probably 1850 era.
Embossed in shoulder seal: RABE
Color: black glass - very deep olive-amber green
Condition: attic mint - perfect structurally, perfectly clean, loads of character and seed bubbles, crude. Maybe a touch of trace wear in spots. A gem.
