As far as I can see, all pistols in the fotos above are made in a typical British style of the East India Company and like these originals have their mounts made of cast brass which are much easierly to produce than iron mounts that have to be forged.
Quite obviously the pistol in question has except the lock and the barrel nothing British, neither the stock nor the mounts, so - and this is my last reply- why should this piece have been made in Afghanistan?
