Sticking just with cowboy guns:
--1894 Winchester rifle in 30-30. 28" barrel, half magazine (a 30-30 version of one of the "family" rifles)
--1895 Winchester rifle in 30 USG. 28" barrel, climbin' Lyman, brass front sight with a flip-up ivory "moon" night sight, or a Beech combination front sight. (Grandpa had one very similar when he made his pilgrimage in search of the Lost Dutchman)
--an Oviedo-made El Tigre carbine, in 44 Largo (44WCF). (For sentimental reasons, they have a good feeling for me that the 92 Winchester never had.)
--1899 Savage--the thinking man's lever action--carbine in 38-55. Lyman 2A tang sight in back, and a Marbles #5 duplex in front. (Strikes me as the ideal ranch rifle.)
--a certain 1873 Shopkeeper in 44 Special, built on a Great Western frame, in .44 Special. (one of my favorite carry guns, disappeared years ago).
