ibought a riviera commander 35 years ago and except for a missing tremelo arm it is still in mint condition. as far as i know they are japanese copies of the baldwin semi acoustic bison guitar. they were available as a 12string, as a bass and even as a double neck 12 string 6 string guitar.i bought mine for the princely some of 89 australian dollars with a hard case. it has always been great to play and it looks good too.
