In addition to what jbmi told you, the SA's with 4-3/4" barrel length seem to generate a little more interest and sell a little quicker. You have a good caliber. The .357 and .38 Spls. don't do so well as the 44-40 and 45LC.
.44 specials are relatively rare and very popular in the First 2 Generation guns by and large. You see more 44-40s in the First and Third Generation guns. First is good, Third the lowest value. Colt has really muddied the waters recently with more affordable guns designed to compete in the Cowboy game that followed the Third Generation guns. I no longer keep up with them but did back in the '70s and earlier. I will say off the top of my head that I don't recall seeing a 44/40 Second Gen gun unless it was a commemorative of some type. I certainly haven't seen them all!
AS a point of trivia I just discovered - During the real "cowboy era" 44-40s were more poplar than 45LC. Why? Same ammo for both the Colt and Winchester. I just learned that. It was interesting to me anyway.
Because the 44/40 is a far better black powder round in a rifle than 45 Colt. In fact there were no lever action rifles in 45 Colt in the old west. The 45 Colt rim is smaller leading to extraction problems and the 44/40 shoots much cleaner due to the brass being thinner and of slight bottleneck design.
