Afghan Rifle Combination Tool

[Tony PP]

Hello, I have a small primer flask looking nearly the same as yours but without the tool. Mine is missing the part from the larger end. All there is is a hollow with a small threaded hole in the middle. I have seen one before that had a small knob that flared out to fit the inside hollow, threaded on the other side and finished with the remains of what looked like a touch hole pricker. It would certainly be easier to fill from the spout end.
Where mine was made -- I have no idea but I was given it in Dara Adam a village on the Pakistan border.
Have fun getting the screw out
