Hi Lunick, I was just looking a the base photo of your bottle. I looks to be marked "60-7", with the Owens-Illinois Glass Company trademark to the right. The "60" marking is a liquor bottle permit number for their glass factory at Gas City, Indiana, and "7" is a date code for 1937. So your bottle is 85 years old. Hope this helps!!
It was made by the Owens-Illinois Glass Company, that is what the diamond marking with the circle around it means. The O-I came into existence in 1929 so whenever you see that symbol it's after this date. About half of all global glass bottles are O-I products today, the logo changed in the mid 1950's so that's the cut off date for your bottle.
If you see just a diamond symbol with an 'I' in the center that is the Illinois Glass Company which dates from 1873-1929 before their merger with Owens.
