And it's a cool revolver! Mine is nickel plated, in .44-40 caliber. (7 1/2" barrel). An historical note: The Royal Egyptian Army purchased 10,000 of these Remingtons in the 1880's. So in Indy's world, he might have come across a few in his adventures there, in the hands of allies or foes.
I'll do a little research on that. I know the Belgians used the Nagant Revolver, and several Belgian-built variants. So he could have very well used one of those.
