As waidman posted, the original Virginian was made by Hammerli of Switzerland and imported by Interarms back around 1976. These models were fixed sighted and were designed after the Colt SAA; available in barrel lengths of 4 5/8", 5 1/2 ", and 7 1/2" and in .357 Mag. and .45LC. They were blued with a color case hardened frame and a nickel plated trigger guard and backstrap.
A short time later, Interarms opened a factory in Virginia to begin production of a new larger scale single action revolver, the Virginian Dragoon. It was available in a blued finish or stainless steel, with 6", 7 1/2", 8 3/8", and 12" barrel lengths and in .357 Mag., .41 Mag., .44 Mag., and .45LC. There were also models designed specifically for silouette shooting as well as the 5" barrel fixed sighted Deputy model. Production for all models ended around 1984.
