have the distinctive "Diamond-O-I" marking just under the "7".(Note: The "I" can appear as a dot in the middle of this mark like with this bottle, though on most it is a more or less distinctive "I".)Reading down through the narrative in Question #11, we find out that the number just to the right of the Diamond-O-I mark is the last two digits of the year the bottle was manufactured, which on this bottle is a "46".As the information under this question notes, ACL's in the U. date no earlier than 1933 and are still being made though most American soda bottles with this feature are from before the 1980s.the makers markings on the base - we can still make a reasonable determination that this bottle almost certainly dates no earlier than 1933 (ACL, lack of bubbles) and could be as recent as the 1960s (straw tinted colorless glass).Once the likely bottle age or date range is determined, some examples of other places to look for more information is provided.: -It is about 9" (23 cm) in height and 2 3/8th inches (6 cm) in diameter.-It is made of thick, heavy glass for its size, weighing almost 1 lb.
This site contains very limited information on specific companies that utilized bottles; such information is impossibly beyond the scope of this (or any) site (or book).If one looks closely at the thick glass in the base of the bottle, one can see that the glass is not quite perfectly colorless, but instead has a slight "straw" or washed out amber tint to the glass (picture of base below).This is a result of using arsenic and/or selenium as the glass decolorizer.This bottle has neither of the closure types noted; it instead has a crown top.Thus, under this question the bottle classifies under option "C" - Other Closure/Finish type with no further date refining possible under this question.
