First, I would like to say, this is an Italian forum so please, write in Italian.
I understand Italian language but it's difficult for me to write in Italian. You write in Italian and I will write in English if it's OK.
In catalogs (not only Sassone) isn't correct information about Fiume 10 fil. stamps with machine overprint.
There are many more than just "few" or only inverted stamps. Everything started in 1950's with Mr. Diena's Fiume catalog.
@REGNO DEL SUD
I really must have scan to see the overprint. There are many very good forgeries. I can see the difference and be sure only if I have big picture.
Perhaps someone can help you to make big scan.
