Middle eastern musket ID help

Hi Blacksmith.
Thanks for all the additional photos. Don't know where to start. LOL Here are some additional observations:
LOCK: The lock, trigger, trigger guard, rear sight, and rear sling swival all appear to be from the French musket posted above. The trigger guard just engraved to suit local tastes. The lock even uses European pan head screws.
STOCK: That decorative wrist plate looks very similar to ones you see on Ottoman/Balkan style horse pistols, just larger. That long, brass muzzle cap is also something more likely to appear on Ottoman/Balkan style guns. Again, to suit local tastes. The brass butt plate being a locally made item.
BARREL: I believe this barrel started life as a European made item for use with a flintlock. The barrel being recycled with a locally made percussion bolster added. You can see the weld thread. The engraved brass overlays being added to the barrel, again for local tastes. The breech plug and breech look robust, and of European manufacture. I'm not sure about the barrel marks. The E with a circle around it may be a Belgium proof mark (?) It might be worth posting the barrel mark photos on the European Forum to see if anyone can identify them.
Overall, it is a very neat and interesting gun. Nice find.

SHOOTING THE GUN: If you decide you would like to shoot the gun, I would recommend you have the barrel inspected by an experienced muzzle loading, black powder (not modern) gunsmith for his opinion. I would have him remove the breech plug and check for plug to breech thread integrity. While the plug is out you can do a good cleaning and inspect the breech. As long as there is no deep pitting, the barrel (since it's smoothbore) can be burnished out smooth again. Also, get his opinion of the percussion bolster strength and the threads for the nipple. You will probably need a new musket size nipple. If the bolster threads for the nipple appear too worn or loose, the gunsmith can insert a new heli coil.
