Yes, I'm referring to that entire family of Colt revolvers listed in the rules under the 1892 banner. Mine just happen to be the 1895 variants. The reason I ask is that the rules appear to be very specific in reference to the 6" barrel in talking about the use of other more modern revolvers in place of real period guns.
1892- Colt M1892,4,5,6,01,03 DA revolver .38 LC (41 Frame)
Those wishing to use the later model Colt .41 frame models (Army Special/Official Police) may do so if in the following configuration: 6" unshrounded light barrel, fixed sights, blued, Square butt. "Officers" models may be allowed if proper to the portrayal.
Later S&W K frames may also be used if having a 6" unshrouded light barrel, blued, fixed sights, ROUND butt. NO "Officers" models allowed. S&W did not offer such a model in this era.
