Could be part of the sn, could be an inspector mark
Gun Registration...
the bottom of the gun
Could be an inspector mark, tracking mark, etc..
Impossible to answer the value question without seeing the gun. Does the W appear on the receiver itself or the bottom of the link? sales@countrygunsmith.net
The gun was made in 1966.
The letter of the given serial number indicates the year the gun was manufactured. In this case, the gun was made in 1960.
It can be part of the sn, it can mean experimental, it can mean duplicate.
Looks like the serial number to me.
Track production.
Mismatched gun, and an incomplete serial number on the receiver.
It depends on what you mean. If you mean that you want to find the age of the gun based on the serial number, there are a few online sources, such as the Blue Book of Gun Values. If you mean that you want to find out if it is registered, no.
Need to know if it is 12ga or 16ga. Your serial number may be incomplete. The gun may have a letter and or letter/number associated with the serial number to determine age. If not it is a very early gun. please check and ask again
