You did not provide the serial nubmer. You will have to call Browning.
The Browning Auto-5 with serial number A 79963 is generally identified as being made around 1926 by FN (Fabrique Nationale) in Belgium for Browning. This would make it a very early Auto-5, which began production in the early 1900s. Because serial-number records for many pre-World War II Auto-5s are incomplete, the exact year should be treated as an estimate. For the most reliable confirmation, you can compare the serial number with Browning’s official historical records and check the markings on the receiver and barrel. Overall, 1926 is a reasonable estimate for an Auto-5 marked A 79963.
