No published sn data that I know of.
1970's-1980's probably.
I would need to know the model number to your shotgun,along with the type which would be single shot,or a double barrel,along with the overall condition of your shotgun.The number provided by you is the serial number.
Check the frame and barrel
CHeck the barrel and receiver.
No way to value with just the serial number.
On the bottom side near the triger
SN not required before 1968
What year is a Parker Shotgun Serial number 126212
The serial number to a browning shotgun made in the year 1989 will have the letters PN found some where in the serial number.
I have an older amadeo coach shotgun by rossi, it is nickel plated. Can you tell me if that is the way it came. Is it a shooter or wall hanger?
Depends on model and when it was made. I have a Stevens 84-C that has no SN on it.
