Hello,
has anybody ever seen this one?

Me and my associate think it is some Chinese copy of something, but I am unsure, looks similar to Thorn, but cannot find a name.

Thanks to everybody.

This appears to be an It Light "Smath" i found this one in a 2015 catalogue, these aren't very known.

Thank-you very much for the hint.
It is just a brand of Fonderie Viterbesi, which is not that credited for public lighting in Italy.
