The two lenses in the light are pop rivetted into the cover - yes, pop rivets.
Backing is cast pot metal, cover is stamped steel. Don't know if the backing has any manufacturer anywhere on it - didn't remove it from body. Cover has no marks at all. The lenses ARE Carello but in all my eBay searching, under Carello searching for my GRP4 tail lights, I have never seen this plate light.
Common sense says if it was Alfa, or Fiat, or Lancia I would have come across one. I think it is unique to the Pantera.
