Help me with these chess pieces

Hi everyone ! So, I hope to find some help with these wonderful chess pieces that my dad recently got. He's a collector but these ones are giving him a hard time. He likes to know where his pieces are coming from and I hope that some of you might help us ! The only few things we know are that they were probably made in Italy, it's either brass and silver or bronze and silver and finally there are a few pieces with 'cast' stamped on them as you can see in one of the pictures. Any help is appreciated and my dad will be very grateful ! Thanks
