To my knowledge the model hasn't changed. It was reissued as the FT-79 Texan. The blue label inside my 2012 reads FT-79 Texan, not IB'64 Texan. It's a FT-79 made in Indonesia with onboard electronics. The FT-79 Texan was a production model made at the Gibson factory starting in 1962. Paul McCartney bought one of these, which was built in 1964. Nothing special, it was even right handed. The FT-79 Texan had no affiliation with 1964 until 50 years later. McCartney's 2005 ($5000.00) USA made signature guitar would be the only true IB-64 model.
