Other info came from Google--"Vietnamese flint lock”
The gun is from the mountain tribes of Viet Nam, Laos, and Cambodia called “Montagnard” by the French (meaning “Mountain People”). The Hmong, Degar, and other tribes were included in the French term. They tended to help the American cause during the Vietnam War.
Mine was flintlock. The flints were held in the forged jaws by a resin and string wrap. Some were used as snapping match locks, but the mainspring on mine is very strong and hard to cock, and there are resin remnants in the jaw, so I think mine was used as a flintlock. One report noted that sometimes kitchen matches were used for ignition. The lower jaw arrests on the back on the pan and could set off a strike-anywhere match if a match head were set in the correct spot. One source called this type a “monkey gun”.
Some GI’s were reported to have been shot with these guns, with 9mm pistol cases
filled with cement being used as projectiles.
I think the guns were designed and made by mountain blacksmiths who saw European flint locks and used the idea to build what they could on that principle. The French came into the area (certainly with flintlocks) in the early to mid 1800’s, and one source reported the guns were made from about 1850 to about 1950. Early ones had bands made from pounded out silver French coins. Later ones had brass and/or aluminum bands. Mine has mostly silver, with one brass and one aluminum band. As mentioned above, some were still in use during the Vietnam conflict. Vets reported seeing them for sale in markets during the Vietnam war.
Thanks to all who played the game and offered more insight into this interesting and unusual primitive firearm. Thanks to JTR for posting the original photos. That process is still beyond me.
