Campania was a USA marketing brand owned by McIver. The frames and components were manufactured in Japan but the bicycles were assembled by McIver in California. The brand survived into at least 1976 This one appears to typical of a higher end, mass produced, Japanese frame. The source may be Kuwahara. The serial number may provide further insight on the exact year and identity of the frame manufacturer. Even if the OP isn't curious, I'd appreciate the serial number for my database. TIA.
