Diamond Only Maker's Mark
I am looking for confirmation whether or not this bottle with a single horizontal diamond with no other marks is a. Owens-Illinois bottle.
I suspect that it is, but nine of the literature I've been able ro find mentions OI ever usinga single diamond without some other mark.
And if I'm simply missing the dot, the i, or another part of the mark, I blame it on my old eyes...😆
See photos for the mark and bottle in question.
Thanks in advance for the help.
