Gaunt played three times in the Lord's schools cricket festival for Tonbridge School against Clifton College as an opening batsman and in 1921 he scored 177 in Tonbridge's second innings out of 274 made while he was at the wicket.[3] Wisden Cricketers' Almanack reported that he was "very severe on the long hops with which he was liberally favoured".[4]
While a 16-year-old still at school, Gaunt was picked to play for Warwickshire and scored 5 and 13 not out in the 1919 match against Worcestershire, which was not a County Championship game as Worcestershire did not enter the competition that year.[5] He played in other Warwickshire matches in the school holidays in 1920 and 1921 but was not successful in them.[1] At Cambridge University in 1922, he played in the freshmen's trial match and another trial game, but was not picked for any of the University first-team matches; he did, however, play for Warwickshire against the university team, a ploy often used to try out potential university players, but scores of 0 and 17 did not persuade a strong Cambridge side to give him a further trial.[6] He played in further first-class matches across the summer of 1922 for Warwickshire and his innings of 32 in the match against Somerset was the highest of his first-class career.[7] But after this season he played no more first-class cricket. Unsuccessful in Cambridge University cricket, he nevertheless represented the university in both field hockey and tennis.[2]
He died at Winchester, Hampshire.[2]
