This Bultaco racer was provided by the Factory for well-known rider Tommy Robb to use. Tommy has confirmed that this machine was supplied to him by the Factory via the Irish Bultaco Concessionaire, and that he raced it for at least a year in national and international events (see copy email on file). After this time it was returned to the Concessionaire. Whilst the history subsequent to that it is uncertain, it was presumably sold by the Concessionaire and remained in Ireland, where it was purchased by the present owner from a racer named Jim Mullen in 1977. Mullen had, in turn, purchased it from another racer named Bertie Wesson. The ownership between the Concessionaire and Wesson is unknown. After purchase, the vendor had the engine rebuilt by Derek Huxley, and the machine remained untouched until around 2012 when he started a 'sympathetic' restoration of the cycle parts, this being completed in 2015. A new Seletta ignition system was purchased and the bike was started and run. However, if the machine is to be used, it will require further re-commissioning and safety checks to be carried out.
The Bultaco's frame also carries a second number, M600 470 D6, referred to in the papers, although it is not known where, or why, this number came to be on it. Documentation comprises the aforementioned email, plus another, earlier, email to the vendor.
