Hi Fernando,
First, have you got some special relationship with S. Claus. Esq. to get your gift early, as far as I know he is still revving up the reindeer prior to take off.
Anyway, nice pistol, I looked at something similar a few weeks ago obviously without the Portuguese connection but the top part of the hammer was missing so I let it go. Are you going to fill the wormholes with wax? it can look quite good and not too noticeable if done well. Remember don't point it skyward and try a shot tonight you never know who's flying above you.
My Regards,
Norman.
