which is it. PO8 (luger) or 45 cal (pistol) ????
Serial numbers do not designate calibers. Look on the brrel to ID the caliber.
Usually caliber and/or serial numbers.
The Engine Serial Numbers Must Match The Serial Numbers on the ID Plate of the car......... Also the transmission and differential are serial numbered as well as the engine. The numbers matching refers to those numbers matching the original build sheet on that particular car.
Impossible to answer. Need to know if its a rifle, shotgun, handgun. Need to know what type of action. Need to know caliber. Need to know who made it.
No. Serial numbers aer NOT UNIQUE. They are intended to be unique to a given make and model- but a gun can be rebarreled to a different caliber.
as a rule, yes
Impossible to answer without a serial number, maker and detailed description.
Before we can put a value on it, we need to know what it is. Your question is like asking "How much is a car worth with 79212 on the license tag." Matching serial numbers are only important on a collectable firearm. Hunters don't care what the serial numbers on their guns are and few modern firearms have the serial number in more than one place.
Not really
No way for us to tell from a serial number alone. Serial numbers are NOT unique to any one firearm.
Impossible to answer.
Probably late 1880's
