Another amazing example of the Afghan 'jezail' using sometimes (but most often copies) of the East India Company balemark, the lion coming in after the quartered heart (c. 1810).

In the Khyber Pass regions in 1890s, the Pashtun tribes advanced their gun making skills in copying British weapons, primarily in the locations in Darra Adam Khel, with the British basically turning a blind eye in return for safe passage through the rugged pass.

The dreaded jezail was well noted by Kipling in his famed poetry on these regions, especially in his "Arithmetic on the Frontier" :
"....A scrimmage in a border station, a canter down some dark defile;
Two thousand pounds of education, drops to a ten rupee jezail".

These guns were deadly and Pashtun marksmen were skilled, later the frontier police levy which became the famed "Khyber Rifles" were originally known as the 'Khyber Jezailchi's'.

Gun making in Darra Adam Khel has been well known into modern times, but with the guns of course more the current types, but these 19th century muskets and the Afghan forms still into '30s.
This is the example I found, the same style lion and date 1815.

As noted, the 'Khyber Jezalchis' were formed in 1878, one of the first paramilitary units of the British Frontier Corps, and their rifles were indeed their own jezails. Soon after they were furnished the British Snider-Enfield; then the Martini-Henry.
When Talbot Mundy wrote "King of the Khyber Rifles" in 1919 (based on "Eighteen Years in the Khyber" by Sir Robert Warburton), the copy of the edition I have has a jezail on the face under the title.
