Is the R on the base inside a circle? If so, it might have been made by Rockware Glass Ltd in England whose mark was an (R) in a circle.
Are there any numbers or other marks on the base?
The so called "Wave" bottle like yours was patented in 1940 and used extensively until the so called "Swirl" bottle was patented and first introduced around 1955. There was a transition period between the two bottles that lasted for a few years, but its fairly safe to say that the "Wave" bottle was fully replaced by the "Swirl" bottle by 1960. Hence, your bottle likely dates to no later than about 1960. However, I'm not sure if these time-frames apply to foreign Pepsi Cola bottles. Their transition period could have been sooner or later than those of U.S. bottles.
