Between you, Sharpsguy, Gunner, Woody and now Ed, I didn't have a chance.
The auction ended today, and hopefully I'll have it in my hands soon.
I was shocked to see a Montana Roughrider chambered for 45-70, and with a 30 inch barrel, show up on Gunbroker. I was torn between this and an 1874 Military Rifle. This one showed up first and the price was reasonable.
