Well, I've spent some time looking through my library and on-line for information regarding your revolver. I remember seeing that cylinder release lever in the past and that led me to doubt my original thought that it was a "Khyber Pass" copy. The gunsmiths in these small, middle eastern shops tended to copy everything exactly, or at least the best they could. That means that these pistols often have the names of companies misspelled or other irregularities. I've looked around and found at least one other photo of a revolver with the same cylinder release as the one in your photos.

If you scroll down toward the end of this thread, you'll see a picture of a very similar revolver in better condition. The author contends that it is a Spanish copy, and elaborates about how the Spanish received contracts from various allied nations during World War I and developed an extensive manufacturing business. Unfortunately, none of the information provided in this thread contains any references or supportive documentation, which leads me to view it is little more than "gun show legend". Hope this helps, at least knowing that your friend is not alone in owning one of these.
