Insulator

[Goldenplug]

. Does anybody know if this is a good insulator? The embossing is hard to read on the picture. It reads:
W. Brookfied (error? Supposed to be W. Brookfield?)
55 Fulton st.
N.Y.

Other side is embossed:
CAUYETS
PAT
JULY 25 1865
PAT JAN 25 1870
PAT FEB 22 1870

Top is embossed: 1

Thats a CD133. Not rare in aqua, maybe $10. You want that one in a good shade of green or purple.

I agree! I love finding them. When i saw it sticking out i thought it was a roundbottom ginger ale.
