Let it be!

However M. BUCCELLATI — 20 century, high-tech. Indeed, flows of tourists. Primarily Americans.
In the mid-70s, my grandfather brought back from Paris and gave me a screwdriver, on which was written MADE IN GERMANY. This is understandable - the European Union.
But strainer (silver French) — old (semi old). Where there could take ITALY? Compare the inscription (the second — from Mario Buccellati):


The first inscription - low-tech. Surface - clumsy. Maybe the master has bitten her? With anger? ;)
If there really is written ITALY, then it is not an old tea strainer, but modern, probably Chinese fake. Why not? Chinese - very talented people! But with the stamps they are not all right.
Kind regards,
