Some years back Hermann Historica (auction 60, lot number 21) sold this matchlock gun. It had damages at the stock and some other defects (like the tang and serpentine which has been broken).
No expert as of yet on these weapons, but i think the auction labbeled it right as a German matchlock gun. It has the same kind of decorations as the Wheel lock carbine from suhl i used to own. So possibly suhl (not sure though
)
third image: the middle one is how it looked like, the others are just an attempt from my side to see how it might have looked like when restored.
