This, from a French magazine, Gazette des Armes, December 1986, article by J R Clergeau on firearms from Siberia, prior to the introduction of industrial-age weaponry from Imperial Russia and the Soviet Union.

Here are two examples, with snaplocks of differing design. The example in the black-and-white illustration has the combined frizzen and pan-cover of a true flintlock, as seen on the Swedish Göinge-bössa posted above, but with the downward-acting mainspring of the 1654 Russian snaphaunce in the Kremlin Armory. The gun in the color photo is a snaphaunce with separate frizzen, and an upward-acting mainspring of the Swedish and Norwegian locks shown two posts previously.

So it would appear that the locally-made firearms of Siberia did not mechanically conform to any single precedent, but rather exhibit varying features depending upon the maker's preferences.
