Serial number X29547 is correct for a 16ga Auto-5 made in 1949. The FN indicates manufacture by Fabrique Nationale in Belgium and is not a part of the serial number. Just because it is 16 gauge does NOT make it a 'Sweet Sixteen.' That was a very specific variation of the Auto-5 with certain modifications to reduce weight by some 10 ounces less than the standard weight Auto-5. It should have "Sweet Sixteen" engraved on the left side of the receiver. Value depends on condition, which of course you dont tell us. So figure a value range of $300-$1000 for a plain barrel gun, add up to another 50% if the gun has a ventilated rib barrel that is original to the gun. sales@countrygunsmith.net
