Marked with a "C B" on bottom with a raised dot between letters

From my brief internet research this appears to be a Chow Chow or English Pickle Bottle made by the English company Crosse & Blackwell.  Please judge for yourself as I am not an expert.

Lovely green bottle has applied lip. There is some excess glass slop over at the lip. There is larger amount of  slop over at the bottom side at the seam on the interior. The bottle is somewhat out of round at the base.

Measures 7 7/8" tall x 3" maximum diameter

Weighs 15.6 ounces

Please ask questions if you have them.
