No serial number given.
The 5G prefix to the serial number indicates that your browning was made by FN of Belguim for browning in 1965.
Impossible to tell from just the serial number.

Acier Special-C.12 Gauge Serial#384034 okg895 Fabric National D Armes Fabrique De-Guerre Herstal-Belgique what is this gun worthy
About 1913 for a Colt police positive special with that serial number.
1877 if it's a Single Action Army. Nothing special about the serial number.
You have a rifle made in Herstal Belgium, probably by FN. We do not know the model or condition, so cannot give you an answer with any real meaning. Sorry.
