Re: Help with jb ronge pistol
It was not a duelling pistol. It was a single shot target pistol, of reasonably decent quality, probably made around 1900. It is missing the breechblock and finding one (short of having a time machine to go back to 1915) will be about impossible. There are lots of those guns around, but even though they look alike they are seldom identical and parts won't interchange.
As to value, even in working condition it would be worth around $100 or less; as it is, consider it a wall hanger.
