What is the date of manufacture of a Browning Double Auto SN A14349 I've looked at Browning's customer service web page but could not match my SN with the information provided. Thanks.?

The Browning Double Auto was designed by the late Val Browning, son of John M. Browning. It was made in 12 gauge only between 1952 and 1971 in Belgium by Fabrique Nationale. There were three variations: Standard, Twelvette and Twentyweight. Barrel lengths were 26, 26 1/2 (Twentyweight only) 28 or 30. Could be had with or without a vent rib. Value depending on condition 400-900. Rare colors will bring more. @ 65,000 were made The alloy frame was available in different colors (royal or light blue, satin gray, green, gold, black and brown. I have also heard of pink and red, but have not seen). For parts try Numrich Gun Parts Corp., (www.e-gunparts.com); 1 866/686-7424). I recommend that you do not attempt to take apart yourself. Call Browning to get a manual The A in your serial# indicates ,Hiduminium Aluminiun Receiver .The #14349 indicates ,with 3600 a year ,I would guess 1956. If it had the letter C in front of the number ,that indicates a Steel receiver. In 1959 Browning started using a code system, an began each new year 's with a ,year number such as 1A or 1C = 1961,followed by the serial #'s 0001 . P.S. for the years 1969, 1970 & 1971 the number of the year precede the letter -69A or 69C, 70A or 70C, & 71A or 71C. These guns were made for 19 years. I have busted a lot of Grouse with a Twentyweight ,with a metric lenght Barrel , just short of 26 1/2" , with a Full Choke , which bust's through the "Brush and Woods" to give a longer shooting field !!!
