The .38 Long Colt was non-heeled inside-lubricated from its very inception (the main difference from the .38 Short Colt)--I'm not sure the date the Short Colt was changed.
The .41 Long Colt change was some time in the mid-1890s. I think (speculation I don't know for a fact) the .41 Short Colt died due to lack of backwards compatibility--unlike the 38 short--> long conversion, the case diameter was increased rather than the bullet diameter decreased).
The .45 Colt (sometimes called a Long Colt, even by manufacturers) and .45 Smith and Wesson aka Schofield (colloquially called the "Short Colt" despite it not being Colt at all) were both non-heeled inside lubricated from the beginning.
Outside lubrication attracted dirt and debris and the military led the adoption of "bullet inside the case".
This is the historical reason that .45s and .41s are still .45s and .41s but .38s are .357" and .44s are .429".
