Persian Serial number

Good Evening All,

I have noticed on the Persians that there is a little translation on the receiver of the serial number to English.
I'm curious to know who does the stamping. :confused:

Cheers,

Best guess would be the importer.

An import regulation, I would imagine.

In Italy it is done by the certifying authorities, the Banco di Prova in Gardone Val Trompia.

That’s mine.
