Shotguns made in the US before 1968 were not required to have serial numbers. Would have to go with whatever markings are on the gun.
Impossible to answer without knowing who made it.
about $100
Not enough information.
On the but
You cannot the serial number is required.
You are stupid ;b
You will have to call Browning with the serial number to find out.
look on the breach, barrel.
Without knowing the maker or the markings on the barrel/breech, you can't find out anything. Even then, there may be little to no information.
The serial number only tells one where in the run & what year it was manufactured in, not who made it.
Generally, you can't. It might be possible with Browning, but, you will need to call them with the serial number.
Depending on the model it can be found on the bottom of the receiver or on the barrel. how to find the year of a belguim browning over and under shotgun by the serial number 53125
