Data Wanted on the TB

Sir,

I recently bought a TB 3-wheeler of approximately 1920-23 vintage. I am hoping to restore it, but unfortunately I know very little about it. It has a V-twin water-cooled J.A.P. engine, 3-speed and reverse gearbox and shaft and bevel drive. It also owns a half-size Bugatti-shaped radiator, with TB on its badge. I have contacted Thompson Bros., the makers, who were extremely helpful, but the information and records have been destroyed.
