Hi floortrader and thank you for responce
You have right on this and I continue searching for the plate and the position but till now nothing.Every picture on internet is like the first plate . As consider the flaws there one more that I found and post the scans.
One more problem is that I cant find the cancel from the first stamp , the cancel with the star down of the date.Up there is an A but I cant see something more.
First

Second

the line is short
The help from expert in Italian stamps and cancels would be precious.
