Restored to 100M factory specification; original matching-numbers engine rebuilt with Denis Welch aluminum head, high-ratio cam levers, high-compression pistons, lighter flywheel, Le Mans carburetor set, cold-air box, and special exhaust. Front servo disc brakes, improved shocks, sturdier anti-roll bars, modified rear axle. Full nut-and-bolt bare-metal restoration a few years ago; restoration fully recorded with many invoices since the late 1990s.
