That applies to BIMAL meds and cures, inks, etc.
Never heard that for Coke bottles.
I already know about the half seam up neck for 1880's bottles.
Please correct me if I am wrong for sodas, specifically Coca-Cola.
According to this website http://www.antiquebottles.com/coke/ the Cokes with a shoulder script date from 1910-1919 and therefore it is most likely ABM.
I think it's ABM but I'd need a closeup of the lip to be sure. The thing about dating bottles by how far up the neck the seam goes isn't true, I think it might be something that Kovels made up. The only way you can use the seam to date a bottle is if it runs all the way to the top of the lip, in that case it's an ABM bottle and dates to the early 20th century at the earliest. (Even then there are exceptions, though).
I have a few Straight Sided Cokes & some Shoulder Script that are not ABM, Like this example below with dissappearing side seam, Lots of Whittle & twisting lines in neck. Whatcha Think? LEON.
