It does look like it could be from 1946. If the B in the middle is a glass maker mark, then it could possibly be from the Buck Glass Co. [ca. 1909-1961]
The blue one is from the Keasbey and Mattison Co. They were located in the small town of Ambler, PA and their company was known for making the U.S.'s first asbestos textile plant. They even have a wikipedia page- https://en.wikipedia.org/wiki/Keasbey_and_Mattison_Company
Funny thing is, I have literally never found a front-embossed bromo. I don't know how that bottle has been avoiding me ever since I started this hobby.
Anybody have any info on this bottle? Looked it up on google but got no results. Made by the D.O.C. glass co and probably dates from 1915-1930. Says "NATIONAL BOTTLING WORKS MINERS MILLS, PA." [higher quality photo https://i.redd.it/dpzi52bdk4w31.png]
Found this mark on the bottom of an old "It's French's" jar. Looked on glassbottlemarks.com, but couldn't find any results that match the logo. Logo is a big M on top of a small A, with the A submerged into the M. Does anybody know what this glass maker is?
There is a C overlapping an L and the number 5 on the bottom, and "Read's" is all it says. Pretty sure the glass company is Carr-Lowrey and the bottle was from Read's drugstore in Baltimore, MD
