Dear potkettleblack, your suppositions could be right if you don't know Italia CAA (ENAC). All italian pilots with italian license, MUST log flight sims on their own logbooks and have them signed by the SFI/TRI/TRE.
In italy our favourite sport is burocracy, so that for example upon reaching 1500 hours to unfreeze the ATPL you need all line flight hour to be signed by the captains.
Anyway, why should I choose a sim I don't know the serial number to log in something untrue in my logbook?
Regards
