Its ABM. I don't have the bottle with me now but I think it had an embossed "2" on the base. There was also an embossed circle on one side which was probably for a label.

Thanks Eric. A bit more info: under the pepsi logo it reads "REGD TRADE MARK." I couldn't get a good pic of the bottom so I will try and describe it the best I can....on the bottom, it has a capital "R" within a circle, across from this there is a "5." Below these it reads "15 A 58" I think...
Here's some I picked up at a local antique shop...1st pic-BIM pickle jar, 2nd pic-Fardons Malt Vinegar, 3rd pic-Worcestershire sauce, 4th pic-twist Pepsi with embossed bottle cap.
