Need Help IDing this single shot

[paid4c4]

Thanks for sharing a very beautiful old pistol. There's a dealer with a large display at the Louisville, KY National Gun Day Shows at the state fairgrounds who specializes in pistols like yours. If you don't have any luck with the ID I'll get his email address for you, he's very helpful. He helped ID a Smith & Wesson .44 Russian I have.
