I just bought a 1873 Winchester, manufactured in 1884, and chambered in .44 WCF (.44-40). I've been wanting one of these for years and finally pulled the trigger (pun intended) when one I've been watching got a $600 price cut. It is rated as "very good" and certified on guns.com.
Of course, I can't find any ammo for it because of the damned fool panic buyers. Maybe by the time it arrives I will have found a box.
Now, hurry up and wait!
