The Triumph TR7p 750cc Saint / Bonneville
The 650cc TR6P Saint has grown-up to become the 750cc TR7p, with 1973 being the change-over year.
In the process it's gained an increase in cubic capacity, a larger fuel tank, a new oil-in frame for both madels from 1971, front disc brake, conical hubs and a host of cosmetic changes and re-worked electrics.
1981 was the final year of production for the Tiger TR7, by which time the police versions of the Trophy and Bonneville were virtually identical, but the Bonneville had twin carbs and continued until closure in 1983. At one point, Triumph had intended to export the Saint to the USA as the new Bonneville.
After the factory closure, the firm of L F Harris took over production in Devon, using exsisting and new parts from Germany and Italy. The resultant machine was known as the 'Harris Bonneville' and many seem to have been in police spec.

According to Wikipedia:
In 1984 the T140 production rights were licensed by the new owner of Triumph, John Bloor, to Devon-based engineer Les Harris who produced 1,300 complete motorcycles at his Newton Abbot factory between 1985 and 1988 when the licence was not renewed .
These machines were distinct from the Meriden product having as standard, German Magura switchgear, Merit spark plug caps with Italian Paioli front and rear suspension, Brembo brakes and Lafranconi silencers.
