To my Knowledge Browning or for that matter any gunmaker has never made a 16 gauge shotgun with a 4in.chamber.In order to get the answer that you seek,you will need to include the model of Browning shotgun in question along with the serial number(to date the year of manufacture) and the overall condition of your shotgun.
It was made in 1970

Starting in 1921, Remington rifles are dated by a 2 or 3 LETTER code stamped on the left side of the barrel, about a half inch from the receiver. Not by the serial number. Search for Remington Collector's Association Date Codes, and you will find the table to decipher the letters for month and year of manufacture. They are small- a magnifier and bright light will help
