Hi Kubur.
WOW!! What a beautiful pistol. Where ever did you find it ? LOL. And it appears to have not seen much use. I can't really add much to Oliver's comments. It is a really interesting confluence of styles. As mentioned, the general stock shape reflects the early wheellock pistols. The white metal overlay on the stock grip and forearm remind me of the early spanish pistols. But, as Oliver mentions, the engravings/motifs seem to confirm it's Moroccan origins. The lock is Spanish in style. A good catch by Oliver is the small decorative plate, just below the lock plate, to fill the gap at the protruded area.
It's obvious this pistol was made to a specific customer's specifications.
Great find Kubur. Wish I had seen it first.
LOL. If you have a chance, please take some more photos. Especially around the pan/vent hole area. Dating this one is difficult. Hmmm......my best guess, using the lock as a guide, might be the first quarter of the 19th Century.
