Guns, Firearms, Projectile Weapon Sports/Iver Johnson serial no.


I have an Iver Johnson pistol (32 cal., 5 shot, hammerless).
It is s/n B52418. I am trying to identify the year it was built.

Thank You very much for your help.

Hello, Arthur.
  Your Iver Johnson Serial Number B52418 was manufactured between 1896-1901. To be exact, there are differences in a patent dates and serial number and their location on the revolver.  I will list them and you can compare with yours to decide which model you have.

         PAT'D.APR.6.86.FEB.15.87.MAY10.87.DEC.26.93.PAT's PENDING

(Side of barrel all patent dates, with the addition date of MAR.13.88, are in two lines )
(Serial number is located on left grip strap B33001 to B66000 )
  These are the only Models and Variations that include the serial number B52418.
Other facts are; These standard revolvers came with nickel plate and a 3 inch barrel. For an extra fee, options included were; 2,3.5,4 and 5 inch barrels. They could also be ordered with wood grips and/or blued steel.
  I hope this has helped you in identifying your Iver Johnson revolver, and thank you for asking for me. Charles Gage

I have been at the study of firearms and their use since my first issue of Field and Stream in 1962.At that time I was completely devoted to rifles, but over the years I have experienced the thrill of the hunt with handguns, shotguns and of course rifles. I moved from Oklahoma to New Mexico in 1972 and, since, I have taken numerous game and non-game animals with all firearms (cannons excluded)including blackpowder muzzleloading rifles,shotguns and handguns. My favorite handgun for large non-game animals, such as feral hogs, is my Uberti replica of a 1847 Colt Walker. Very heavy, but accurate.

I am a 1973 high school graduate. Junior and senior year I developed a class on Wildlife Depredation and Conservation of our Rocky Mountain states. My specialty was the brown bear.
