Value is very much effected by condition but assuming the gun is in very good or better condition it should bring about $2000 ($1500 for gun and $5-750 for extra barrels).
depends on condition- $400-$750
Yes.
open gun where the barrels latchs,the model numbers will be right there.
They probably denote what choke the barrel has.
Rifle, handgun and shotgun can all have "long" barrels
The cartridges will pop out.
Exactly how is the shotgun marked (all markings), and double-check the serial number. sales@countrygunsmith.net
I would look at the number of barrels. If there is more than one barrel, you know you have at least a double barrel shotgun. If there are 1 or less barrels, then you don't.
No
That would depend on the make and model of the shotgun in question,and the length of the barrel/barrels that came with the shotgun.
I appreciate any information you can provide as this was my great grandfather"'s shotgun?
All the serial lists I have on the 12ga Sterlingworth have the numbers starting at 53800 in 1910. Can you verify that number? sales@countrygunsmith.net
