No 'Nando,
It's just Michael the matchlock (and wheelllock

) man, who dares say so by humble experience and a few books.
I'm attaching scans of a characteristic Portuguese wheellock illustrated in Arne Hoff,
Feuerwaffen I, 1968, p. 95f. I don't think this standard reference work was tranlated into English ... Hoff thinks this one might have been copied in Italy, an opinion from which I differ. For comparison, attached please find a characteristic North Italian combined wheellock and snaplock mechanism of ca. 1580: the outer main spring is similar to the Portuguese locks but the shapes of the dog and shell like wheel ornamentation are clearly variant (also from Hoff's book).
Spanish and especially Portuguese wheellocks range among the greatest rarities.
Rainer's book is not helpful as it covers only matchlocks. I'm pretty sure though he has some Portuguese wheellocks as well.
Best,
Michael
