Sour Liquor control? I have this bottle and not suwhre what sort it is and how old it is. But has this stamp.
I am fairly sure that would be Missouri Liquor Control. Do some searching for "Missouri tax stamps" or "Missouri Liquor Control stamps" to see if you can find one of similar design and amount (1-1/4 cents) which will at least help you date the bottle.
Markings on the base may also provide some clues.
