I appreciate those images very much, Spiridonov, thank you!
I should date all these items to ca. 1530.
Actually all these snap mechanisms were meant for a small piece of
tinder (a sort of fungus growing on trees), not match. You can tell by the tiny jaws of their serpentines that they could never have received a piece of match which used to be as thick as a finger.

The thick matchcord - often shown wound around the arm - was then only used to light the pieces of tinder each of which was used for only one single shot.
Do you have more of these? We are eager to see them!
Regards,
Michael
