What is the age and value of a 16 gauge shotgun made by Fabrique Nationale D'Armes de Guerre Herstal Belgique Browni?

Please add the model number(name) and the serial number of your shotgun to get a accurate date and value to your shotgun.

Browning Arms Company Ogden Utah, Made in Belguim. Fabrique Nationale D"armes DE Guerre Herstal Belgique, Hump back 59287 16 guage

I am looking for a butt plate and I will assume that different guages take different butt plates

Any help in identifying how to determine which butt plate would be appreciated
