Crescent Fire Arms made these before 1920 and J. Stevens later. Other markings could determine which company made yours, but the factory batch number won't help.
Not really. There were several companies that used Knickerbocker- most were made by Crescent Arms btween late 1800s and about 1930. Your MAY be from around the end of that time, but records are spotty on the "store brand" guns.
It will be marked on the receiver. It was made in 1980
By the serial number and features.
By the serial number.
Where will be marked on the barrel/receiver.
You will need to list the model number of your western Field shotgun,and then I can cross reference the model number to the maker of your shotgun.
Should be marked on the barrel
It is marked on either the receiver or the barrel.
no it has a 4 digit serial # Knickerbocker came from 2 different companies. The American Gun Company, New York, stamped a five digit serial number on the barrel, forestock and stock end.
By the serial number
The age of your shotgun is determined by the serial number that was assigned to it.if you wish to include this number in the form of a question we will be able to age your shotgun for you?
All my records indicate that stevens did not make a model 337 shotgun.If your stevens shotgun is marked U337 under the receiver,this would be a serial number,not a model number.
