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?
