Hi Kubur.
Not shure where the term "knee" pistol came from. But that's probably as good a description as any, even if not completely accurate.
This style of pistol with the short rifle style butt seemed to be popular only in the Ottoman Empire. With pre-formed combustable cartridges with buck shot, it would be fast to reload - especially from horseback. Would be a great close quarters weapon.
Corrado26: That is a beauty!!!! And in fantastic condition. Super nice!!
Here is a pic of one from my collection. And note the last pic of the guy sitting in the middle hlding one.
