Hello GoodLord,
It was made by Brockway Glass Co. somewhere in the 1940-1955 period. "B in a circle.........Brockway Machine Bottle Company (1907-1933); Brockway Glass Company (1933-1988), Brockway, Pennsylvania. “B in a circle” mark was first used in 1925. In 1964, 10 of the 12 Hazel-Atlas Glass Co. plants were acquired. Brockway eventually had (at one time) up to 16 different plant locations. In 1973, (besides the Brockway PA plant), factories were located at Muskogee, OK; Lapel, IN; Crenshaw, PA; Freehold, NJ; Parkersburg, WV; Washington, PA (2 plants); Rosemount, MN; Zanesville, OH; Montgomery, AL; Ada, OK; Oakland, CA and Pomona, CA.

GLASS MANUFACTURERS' MARKS ON BOTTLES
You didn't mention the dimensions. Bottle diggers call these slicks, due to the lack of embossing.
