Powder boxes from Oman

[Hommine]

Hi I have have listed some powderboxes, firestriekers etc. I bought in Oman. I believe they are quite old. I am particularly interested in any comments on the letter belt with the several wooden powderboxes , these little "pipes" have geometric designs on them that have been burned in the wood. The leather is strung with a lace around the piepes so the powder stays inside. Actually one of them is a bone... Has anyone seen one of these before any idea how old.

There is also a curieus silver firestriker with a nice silver chain. Does anyone know if this was only for decoration or did it have another purpose?
