Brownings made prior to the Second World War could have been chambered in 16 ga, 2-9/16" length. That is no longer a standard SAAMI length and I know of no US companies who load it. You may be able to find a hand loader who can make them for you, you can investigate the European cartridge companies to see if there is a European equivalent, or you can have the gun converted to shoot the longer 2-3/4" shells.
Your browning auto-5 shotgun was made by FN of belguim for browning in 1947.That makes your shotgun 64 Years old.
This is the same as a Superposed model shotgun. Introduced in 1931, Browning still makes these in Belgium.
Your browning model auto-5 shotgun in 16ga.was made by FN of belguim for browning in 1951.That makes your shotgun 60 years old.
You need to identify the make and model of the shotgun. Dozens of different makes of guns show a browning patent on the barrel. Recheck and re-ask the question - Thank you
Browning makes a bps pump model in 3 different barrel lengths and also found a tristar o/u.
No, and no other company makes one either. 10,12,16,20,28, and 410 are what is being mfg at this time.
Your shotgun was made in Belgium in the year 1960.That makes it 53 years old.

your standard weight browning auto-5 shotgun was made by FN of belguim for browning in 1961.That makes it 50 years old.The value of these auto-5 shotguns is running between 475-600 dollars for the standard model auto-5 shotgun.
The barrel will be marked as to where it was made. Browning.com has sn data under cusotmer service. How it compares is a subjective call that only you can make after handling other makes.
Your gun is a Stevens Model 520. Made for Sears, and marked with the Sears trademark of Ranger. Nice pump shotgun, originally designed by John Browning.
