Middle eastern musket ID help

Long awaited pictures, and in reply to the statement about the lock lifting out, you were correct! it popped out. I cleaned it only slightly with a bit of 0000 steel wool, wiped wet, and then a wipe of oil, and im amazed at the beauty of this old rifle after just simply wiping way the surface rust and the crud that had accumulated over the very deep patina. the stock got a similar treatment with superfine sanding of the outer layer of dirt, and a good wipedown with oil. Its amazing seeing the dark patterns of use where the hands and cheek rested. There arent any screws on the left of the stock, however there is a roughly triangular lobed piece of metal recessed into the piece that serves as something solid for the bolt securing the lock to screw into. After it fell out while removing the lock, and knocking off a bit of dried something-or-other, there was a small hallmark of a crown with a W beneath it on that small metal piece.

And now for the big event, some photos of various items. If all goes in order, the following show: the butt plate top. The plate itself is simple metal held by small nails around the perimeter of the butt of the stock, this piece folded over the top is the decorated bit.
Next is the trigger guard decorations. If it helps to ID the gun, the guard removes by removing a screw in front of the trigger and the back of the guard swings out of a slot once the front is free.
Next is a decoration on the grip area of the stock behind where the barrel screws on.
Following that is a view of the breach area itself,
and finally there is an up close view of the metal sheath tht covers the front end of the stock and helps hold the ramrod in place
