By this number alone, this would not be a Sweet 16, but a Standard weight 16ga made in 1929. Sweet Sixteen is a model name given to a lightweight version of the regular (Standard weight) 16 gauge Auto-5. If the receiver of the gun is scripted "Sweet Sixteen" on the left hand side, then you do not have the complete Serial number listed. Your serial number is missing a letter and/or a letter/number preceding or above the 71964. This information is needed to determine the year of manufacture. Please re-check and ask the question again if another number or letter is found, otherwise you have a Standard 16 made in 1929. Thank you.
