The stock looks early
and the lock has some similarities with the Spanish aqujeta but with an internal mainspring . Since it hasn't got a half cock dog do you think it has an additional separate flashpan cover?

Hi Raf
You must have noticed by now that there are two Fernandos going on; the one that knows a significant lot about locks and has been replying to your questions is Fernando K; the one who has posted the petronel picture (and not only) is Fernando (no K), who knows extremely less about the subject.
Perhaps you like to have a look at this link; it will possibly complement the answers to some of your questions about these Portuguese locks:

And by the way ... the petronel you have asked for the precise date in this post, was made in the Lisbon Arsenal circa 1560 -1580.
