Excelsior Model Identification help

[cbeernink]

Hi folks, have come across a second hand Excelsior accordion and am struggling to identify model/era. Or if it's a copy! I haven't seen any images of an Excelsior with 'italy' below the logo. Unfortunately can't get inside to see it's internals.
Can anybody offer some guidance?

Cheers,
Chris
