The stocks have some scattered light nicks, scuffs and scratches. There are a few more notable nicks on the left of the forend at the rear of the checkering, the bottom-front of the grip, and in the belly and a more notable vertical scratch in the left of the buttstock. The checkering is generally well defined. There are no chips or cracks. The LOP measures approximately 14″ from the front of the trigger to the back of the recoil pad, 13″ to the back of the wood, indicating that the stock was likely cut when the pad was installed. The pad has minor wear and is still fairly supple. Overall, the stocks are in Very Good condition.

Our Assessment: The Browning Automatic 5, most often Auto-5 or simply A-5, is a recoil-operated semi-automatic shotgun designed by John Browning. The Browning Auto-5 was the first mass-produced semi-automatic shotgun. Designed by John Browning in 1898 and patented in 1900, it was produced continually for almost 100 years by several makers with production ending in 1998. It features a distinctive high rear end, earning it the nickname “Humpback”. It is also an important piece of Browning/Winchester history.

John Browning had previously sold his designs to Winchester for lump-sum payments, turning over all of the patents related to a particular model. Winchester had gotten in the habit of having their engineers and attorneys assist Browning in filing for his patents, in order to ensure that when they received those same patents they would be airtight. Browning’s experiences with Colt and FN had convinced him that he would be better off licensing his designs rather than selling them outright, but when he presented this to Winchester, they refused his terms. This ended the relationship between Winchester and Browning.

Browning would eventually license the design to FN in Europe and later to Remington for their Model 11 and to Savage Arms for their Models 720 and 755. These designs went on to be a great commercial success, the first truly successful autoloading shotgun. This Auto-5 was built by FN in 1950 with Grade I engraving on the receiver and tangs. It is a desirable “Sweet Sixteen” model, made in the X-prefix serial range and just a couple of years after the Sweet Sixteen moniker was actually engraved on the receivers. The gun has had an after-market ventilated rib installed as well as a Weaver Choke, making for a versatile hunting gun. That said, this vintage Sweet Sixteen may also attract the collectors.
