I have the opportunity to purchase an Iver johnson where the trigger does not work because of a spring mechanism, (a guess.) The gun itself has stamped into the metal, or nickel, on the top flat part of the barrel, Columbian F. A. M'F'G ing Co. Phila, P.A. U.S.A. 2nd line Pat. Dec 11, 1894 PAT. P.D.G. the serial number, which i think is the serial number, is on the bottom of the handle of the gun. 25436 i believe, which is odd i think for an iver johnson revolver. Come to think of it the gun does not say ivor johnson on it. Can someone tell me what this is? how old it is? and if it is worth 45 dollars? and could i sell it for 80 dollars? or how much? and is it legal to do so? i would really appreciate it as i am out of my area here. thank you.
