Serial numbers were not required on long arms before Jan 1, 1969. Most manufacturers did not assign serial numbers to small caliber rifles or utility shotguns.
Volunteer was a trade name used on shotguns manufactured by Crescent Fire Arms Company for Belknap Hardware Company of Louisville, Ky in the period 1893 to 1930. No records exist to give a serial number, date of manufacture. Value for a .410 would average at $100-$125, depending on condition.
There may not be a serial number on the gun. If that gun was made before 1968, .22s & shotguns often did not have serial numbers. In 1968, a law then required all firearms to have a unique serial number.
No published serial number data.

Diamond Arms was a trade name used Shapleigh Hardware for guns that were actually made by Iver Johnson of Fitchburg, MA, c. 1920-1950. Prior to that, they were made by small local makers in Belgium. These were utility grade guns.

About $100.
Seldom above 150
While there are several gun manufacturer\'s that offer serial numbers on their shotguns, unfortunately the Mississippi Valley Arms Co. does not. The year and gauge of the gun would depend on when it was manufactured. For example, Mississippi Valley had numerous shotguns produced by a subsidiary company called Crescent Firearms, while many were imported from Belgium.
A 410 gauge, single barrel shotgun with Volunteer stamped on it and Serial number A981277 was made by the Volunteer Arms Company. They made guns for Belknap Hardware store in Louisville, Kentucky.
