interesting Old Overholt bottle and dating question

[cowdery]

One practice that took place in the immediate post-prohibition era was for liquor companies to pay dividends to their stockholders in the form of whiskey. They usually made it something special in terms of the packaging and often in terms of the aging and other characteristics. This was done immediately after prohibition if the company still had pre-prohibition stock it could bottle. It also happened in later years as post-prohibition distillate began to mature. Anyway, it sounds like these could be "dividend whiskey."
