It looks like something I would shoot modern smokeless ammo in, only if I wanted a colorful nickname, such as "Three finger Ron" " or Old one eye RJ " It is a old Belgium Gun, probably dates to the 1920;s or even earlier. These were made by the boat load for export to Europe and the US. they sold for very little,primarily through catalog sales ( 2 to 3 dollars ). Value wold not be high, 100 to 150 as a curiosity or to to a collector who wants to fill a hole in his collection.
What are you folks seeing in that picture? I see part of an engraved revolver, then what looks like a Rorschach inkblot test. Is this some kind of new artistic way of depicting guns?
