Judging from the ejector rod style and that of the stocks I would say the top revolver was most likely made during 1945 or '46. Remove the stocks and look at the inside of the panels to see if one or both are serial numbered to match that of the gun. The revolver’s serial number is stamped on the bottom of the butt, and likely has a letter “S” prefix.
If so, the “S” is to show that while it has the pre-war style “long” double-action which is hard sought after by some, it also has the post-war positive hammer block that makes it safe to carry with all six chambers loaded.
These are often called Transitional Pre-Model 10’s. They were only made during 1945 and ’46, and represent a bridge between the last of the pre-war revolvers and the new post-war ones with a “short” action that was introduced in 1946 and made forward to today.
I have no idea what you paid for it, but I suspect it's worth more then you think.
