The big Jags couldn't hack it in Australian conditions,insufficient cooling.I like your bald tyres,in those days they were nt worn out until the canvas plies showed thru,bike tyres were the same.I had lots of small pommy sports cars,the best was a Singer nine ohc,the worst was a Triumph Spitfire Mk III.What a pos,if you dropped back to third gear and floored it,the layshaft would break teeth,fix that and the diff gears would break teeth.The twin SU carbs would often fall off the motor.My brother had around a dozen Berkleys in various states of disrepair,they had a two stroke motor with no cooling fan,seizure was an everyday occurrence.And people wonder why the British car industry died.
