I've got an identical gun: 1860 Army with Navy grips, same 8" barrel in 44 but made by Armi San Marco and sold as a "44 cal 1861 Navy". Now I'm tempted to put navy grips on my ASM Hartford model 1860 Army to have a matched pair.
With over 15 perCUSSIN' revolvers, I've been called the Imelda Marcos of cap & ball.
