I only have one Civil War era firearm and it was not used during the war. It's a Special Model 1861 Contract Rifle-Musket manufactured by Lamson, Goodnow & Yale Co. with a 1863 dated lock. It is in unfired condition and I acquired it from my father in law's neighbor who resided in Montana. It hung above a fireplace for over 90 years and looked almost black when I got it. I wiped it down with Murphy's Oil and what you see in the picture is how the wood turned out with just wiping the dirt off with a soft rag.
Thomas Francis Meagher, the acting Governor of the Territory of Montana, asked the US Government for arms and munitions to arm the Montana Militia. After quite a bit of research, this rifle is believed to be one of that shipment of arms delivered to the Territory in 1867. The rifle had been handed down through the family and as far as they knew, nobody had ever used it. It came with a bayonet and scabbard. The bore was packed with cosmoline or something like it and when I cleaned the bore, the breech plug was as shiny as a new dime. The underside of the hammer shows no wear and the nipple looks like new. The cartouche looks almost as crisp as the day it was stamped. The underside of the barrel looked like polished stainless and I'm sure I was the first person to remove the barrel from the stock after it was assembled in 1863.
I was at the museum at Fort Harrison in Helena and there were some rifles displayed that included a LG&Y and when I asked the curator about them, he told me they were "Meagher" rifles and part of a shipment to the Montana Militia. That's what started me on researching this rifle as Thomas F. Meagher was a direct relative of my great, great grandfather. It was amazing to me that a random firearm purchase indirectly led back to one of my relatives back in 1867.
