Hi Dom,
As I wrote already I stroke sail .....so I do not understand.
Of course before I made reference for Tirri´s book I went through it. But If you are going to be precise, there is one for Tuareg (of the type presented here)
. And I believe you for hundred % - Tuaregs did not use guns in 19 century, they started in 20 century
.
(But desperately really - I fully understand gun is not their original weapon. And BTW - Years ago I visited 6 times Ghadames and two times Ghat, which were considered to be part Azjer Tuaregs territories before, and I saw some old photos in a small private museum in Ghadames - maybe armed accompanions of caravan...)
best
Martin
