I have one of those medals from my dad's line and have been looking for more information about where exactly he served. I do also have a certificate that appears to have been given along with the medal. I also know that my family was from the Avellino province and my grandfather and great grandfather received in the mail (to their homes in Italy at the time) a detailed record of their service from the Province of Avellino military office. I have them but can't translate them. My suggestion would be to find the closest office to their homes. It's a long shot but I know that's where mine came from.
