Dating bottles by their tops


Found one today, small glass bottle marked with John Diamond Philadelphia, PA USA in center a circle with a line intersecting through one part of it. Can’t find anything on that one, any ideas?

    One unique closure to the late 1930s was a three point screw top.  Unlike most screw caps, the three point screw top had three lugs jutting out from the lip which were to engage a metal cap.  This closure can be found on Whisky and medicine bottles of the 1837-1940 period.
