Hey Guys,
Each of my holster patterns come with ten different patterns. They are designed to fit: Remington 1858 w/8" barrel, Remington 1875 w/7 1/2" & 5 1/2" barrels, Remington 1890 w/5 1/2" barrel; Colt 1873 SAA, Bisley, Thunderer and Lightning in 7 1/", 5 1/2" and 4 3/4" barrels; Colt 1860 w/8" barrel; Colt 1851 Navy w/7 1/2" barrel; Ruger Vaquero, New Vaquero, Bisley Vaquero and Bird's Head Vaquero, with 7 1/2", 5 1/2" & 4 5/8" barrels; and, Smith & Wesson Schofield w/7 1/2" barrel. They may fit some other wheel guns as well, but there is no sure-bet.
On the earlier patterns, before Ruger came out with it New Vaquero, the Colt holsters aren't labled as fitting the New Vaqueros, but they will. Also, most of the early Colt 1873 holster patterns will fit the Remington 1875 and '90 without modification.
I hope this helps,
Will
