Could you happen to know around what year it has been made?First off, welcome to the FORUM. Can't identify it specifically, but it looks like a pin-fire revolver of European origin. Pin-fire was used mostly in French made firearms, so my best guess is that it comes from there.
Just guessing, from the 1860s up through the late 1880s. Many of the 19th century European made pistols had bag shaped grips like this one does. Another is thought it could be Belgian made also. They are in close proximity to France and made guns that were cheap knock-offs of all that they were copying. The Belgians made cheap guns for world markets and for here that was described as the "Hardware Store Trade". Inexpensive usually poorly made (usually inferior materials) knock-offs of higher quality firearms. It could be one of this genre'.Could you happen to know around what year it has been made?
