Gary Maddox provided us with this picture, which was taken outside of a bike shop in Japan, summer 1996. The sign says generally:
"Maha 750 (their version of Mach), experienced riders only. Exported to the US 1972, returned to Japan unridden. All documentation. 1.9 million Yen (or 18,095 USD at 105 Yen/USD)."
