Most of these as pictured were made in the souk as souvenirs of the North African campaign for the allies; many were for USA GIs. I have seen ones for the French and British soldiers but I would suggest this is likely for a USA serviceman and some had dates etched in and some did not. The turks head mark may be what you are seeing on the back which makes it correct for the area of production. These continued to be made as souvenirs post war so it could be one of those as no date is on it. The greatest amount though came through pre 45 largely because of the large allied armed forces numbers looking for souvenirs and mementos.
