The Millbrook Sale | Milton Keynes, Bedfordshire

 
Lot 5
 

1957 Triumph TR3
1 of just 1,286 home market cars

Sold

(including buyers premium)


Lot details

Registration No: YYA 377
Chassis No: TS17027
MOT: Exempt

  • Only three registered keepers from new
  • Understood to have seen past competition usage
  • Self-evidently the subject of much restoration work over the years

Introduced in 1955, the Triumph TR3 contested everything from the Monte Carlo Rally to the Sebring 12-Hours via the Mille Miglia. Powered by a 1991cc OHV four-cylinder engine allied to four-speed manual transmission (with optional overdrive), the newcomer was capable of over 100mph. Tough and agile in equal measure thanks to its box-section chassis, independent front suspension and responsive steering, the model gained front disc brakes during 1956. America accounted for the vast majority with only 1,286 being allocated to the home market.

First registered in Somerset on June 1st 1957 (or so its ‘YYA 377’ number plate would imply), chassis TS17027 is understood to have had just three registered keepers from new; the first and second of whom retained it for twenty-five and thirty-three years respectively. Believed, like so many of its siblings, to have seen past competition usage, the Triumph has self-evidently benefited from various restoration works over the years. Treated to a new tonneau cover to complement its hood and sidescreens in 2017, the TR3 had attention paid to its ignition system, carburettors and front disc brakes during 2020. Deemed by the seller to be ‘great fun to drive’, ‘YYA 377’ is now looking for its next long-term custodian.
