Hello Mauro,
Do not handle the pistol too much, otherwise you might wear off the fire blue on the grip screws!!
Moreover, after 80 years or so, the ivory will turn a beautiful yellow color, but you might not be around to see it. However, your son might have the pleasure to notice the change!!
The next time I visit you, I am looking forward to drinking that bottle of Italian sparkling wine. Should I bring one of my vinatage ivory corkscrews to pull out the cork? By the way, my corkscrew shows an example of the color I am mentioning
Ciao,
Albert
