Just bought a double auto and it's a steel receiver model with just 296 stamped on the receiver, this would appear to be a 1952 model. Like all modern guns are the barrels on these guns stamped with the same serial number? I ask as mine isn't but still has a 1952 code on it.
The 16ga number 1 began in 1909. The two sets of numbers are different. A common mistake I have seen in many, many, gun shops and online sites is to assign the 12ga serial number date to a 16ga. I compiled this quick reference serial number guide for dating 16ga Browning A5s and the Auto 5-3 Shot, by serial number.
