No worries. I found this online:
''Have not been able to find a great deal of information on Oria, apart from the tubes were drawn by Mannesman. Oria was based in Verona, it was good quality and sold to local framebuilders. Primarily used on Italian bicycles, by manufacturers like Pinarello, Benotto, Moser, Montagner, Daccordi, Olmo, amongst others.''
