Only by comparing it to known products of the possible makers. Joe Vorisek's book lists the makers as Crescent, Crescent-Davis, J. Stevens, and Iver Johnson. But since Stevens/Savage bought Crescent and Davis, and operated them as a separate company for a few years then took over the line as Stevens, there will be identical guns from those three company names and no way to determine if it was made in 1925 by Crescent, 1930 by Crescent-Davis, or 1935 by Stevens.
some one but u will never know hahahahahahahahahahahaha lol :)
No sn data published.
You will have to tell who made it.
No published sn data.
The Excel shotgun with serial number 42080 XG was made in 1992. Excel shotguns are known for their quality and craftsmanship, and the serial number can provide specific information about the manufacturing year. If you need more detailed information about a particular model, it's best to consult the manufacturer or a firearms expert.
Yes.
Have it examined by a gunsmith
It will be marked on the receiver. It was made in 1980
The barrel will be marked "Made in Belgium"
Excel shotguns were made by Crescent, Crescent-Davis, Iver Johnson, and J. Stevens. If it was made by one of the first two, the number probably isn't a true serial number and the exact age cannot be determined. There are a couple of experts who MIGHT be able to place one of the other two into a range of +/- 5 years.
Numrich Gun Parts Corporation have most, if not all of the parts for an Excel shotgun. They are located in West Hurley, NY.
This is the default behavior in most (all?) versions of Excel. You have to go out of your way to tell a spreadsheet NOT to do this.
