The Brockway is a medicine bottle of similar vintage. "Brockway………….Brockway Glass Company, Brockway, Pennsylvania (1907-1988). See “B in a circle” mark. Most bottles I have seen with the cursive “Brockway” marking, usually embossed on the base, seem to date from the 1950s-1970s period, although I do not know the exact period of use of this mark."

I used to work in a foundry in Franklin Pa. named Franklin Bronze and Alloy. We cast all the pieces for Brockway Glass for blowing and forming the bottles. I came across your thread because I also recently found a "Whitehall" bottle and was looking for info.
