Rear Frame no. RC/1/6093 Crankcase mating no. 92H/92H • Present ownership since 1986 • Matching numbers example • Big bore conversion to 630cc • Electric start and modern improvements Announced in late 1948, the Comet in Series C form was equipped with a higher compression ratio than the Meteor, front propstands, Girdraulic forks, and different rear frame. PFC 997 was acquired by the deceased owner in 1986, being purchased from Brian Thompson In need of restoration, the vendor advises us that the engine was passed to well-known Vincent engineer Bob Dunn for rebuilding. The owner, who was no slave to tradition for the sake of it, decided from the outset that it should be a little different to (and faster than) the average Comet. To this end, he resolved that it would be a bigger bore and stroke of 90 x 100, resulting in a capacity of 630cc, utilising a 9:1 compression J & E piston, Carrillo conrod and special crankshaft. A Mark II cam was used and a 36mm Mikuni carburettor, with a Lucas Rita electronic ignition system and coil ignition. A Norton gearbox and clutch was felt to be superior to the original Burman, and an electric starter was employed. Improved braking is brought about by use of Black Shadow-type front drums and Lightning-spec brakeplates. Needless to say, the electrical system was uprated to 12 volts, a solid state voltage regulator and halogen headlight unit were fitted. The work was completed in 1999, and the Comet was used regularly from 1999 to 2009, the owner keeping a detailed notebook, included with the bike, of mileages, work done, and journeys taken. When the owner became less able to ride the machine, it was decided to attach a sidecar to the bike and a Watsonian Monza Classic in GP Jubilee form was ordered and subsequently fitted by Watsonian in 2013 at a total cost of £5,560 (invoice on file). Unfortunately, the owner was unable to enjoy the outfit, except on a few occasions in the sidecar. However, the bike has been kept in useable condition and run at intervals since the deceased owner passed away; in 2017 it was ridden to the VOC summer rally, and will be capable of use by a new owner with little more than a basic check over. Documentation accompanying the bike comprises a current V5C, a continuation RF60 buff log book dating from 1959, a number of old MoTs, the aforementioned notebook and invoice, assorted invoices, plus sundry papers.
