Matchlock Pistol ?

[fernando]

Sorry Michl, i am a bit lost with your comments .
Do you mean to say that this XIX century pistol doesn't have a spiral (helicoidal) main spring ?.
Note this is not my idea; i am just translating the book text. This pistol surely belong(ed) to the author's collection; he must have examined its interior.
... Or am i misunderstanding you ?
