I can say that in the last 2 years I have bought a 10-5 and a 10-7 both with 2 inch barrels in much better cosmetic condition than yours and both were in the 350 dollar range.
That's sort of an apple/orange comparison. Model 10's number in the millions while less than 200K post war S prefix's were produced. I'd give $375 for the OP's revolver and pass on a Model 10 in much better condition at the same price.
