Michel lists two counterfeits (to defraud post) and these two have huge CV:
Naples (Napoli) and Rieti & Aquila.

`According to the book: 'Postal Forgeries of the World' by H.G.L. Fletcher, a postal forgery exists, but it does not resemble the above forgery (this postal forgery has a very long upper part of the 'T' and 'E' of 'POSTALE').` Scroll down:
