All older Smiths...
A blued .32-20 square butt new enough to have the easier to see sights and hardened cylinder. I have my nickeled gun, but have wanted a blued 5" .32-20 for a while.
.455 Mk II., preferably shaved to .45 Colt. Not much on that long 6 1/2" barrel, though.
Or, a franken-gun I found on Gunbroker years ago, one that to my mind was the ultimate N-frame: A 1917 that had been re-cylindered or something to .45 Colt.
I like .45s and 5" barrels as much as .32-20s and 5" barrels. And am already set up for both .32-20 and .45 Colt reloading...
