Hi Chris.. can you send pics and I will do some research for you here in Italy.
I would attribute much of this "character" and quality to the era .. the 50's Italian boxes look, play and sound like no others in my opinion.. ( the old button Soprani's go for $1,500 - $2,000 .. and ANY Italian 50's.. and I daresay 60's box.. in good to mint condition will satisfy.. )..
Workmanship and materials have since been lost.. IMHO.
This of course has nothing to do with LA boxes which the Italians ( despite the materials ) can't touch.. ( I have shown some builders and they are impressed..but don't understand the tuning at all ).
