Iver Johnson Wagonmaster
Made (off and on) between 1985 and 1990 in .22 rimfire and .22 Magnum, the Iver Johnson Wagonmaster is basically the same gun that Henry is now producing.
It has an 18 1/2" barrel and the magazine holds 15 rounds.
It had been marketed by Ithaca during the 1960's and was designated by them as the Model 72 Saddlegun.
The rifle was a development of Erma in Germany.
