Thanks for the input, Dana
Yes it is mine; some swap i made last Friday, with some extra from my side
Mind you, patilla (or patilha in portuguese) refers to the hammer toe as its shape resembles human hair sideburns.
Yes, the battery appears to have a replaceable face.
I didn't yet decide to dismount the lock foor possible interior marks.
No the the butt style is not Catalan but Brescian. The catalan butt looks more boot/foot like.
No there are not pins fixing the barrel to the stock, only bands. Maybe you are noticing some wood imperfections.
The is or was no trigger guard; both side and counter plate pictures will be posted soon.
Yes the screw that holds the tang is in the 'inverted' position, a method also used in early Portuguese examples.
I agree that the decoration doesn't look Moorish at all. On the other hand, it is known that the patilla (Miquelet) lock was brought to Italy during Spanish domination ... if i put it correctly.
