Peter was one of the biggest men in the team with an extraordinary chest development which he put down to having to start his day at boarding school with 50 or more push ups. This school was Sedbergh, the alma mater of many rugby internationals including Wavell Wakefield, Will Carling and Will Greenwood. He was a superb tackler, a dynamic, bustling rover in the loose and a proficient line-out specialist. Highly rated by the All Blacks for his tight defence, he tackled strongly, had a high work rate, covered effectively and actively supported both backs and forwards in attack.
He played some of his best rugby on tour. He played in 16 matches on tour including three of the Tests in New Zealand.
He had been made captain of Scotland in their last international match before the tourists departed to ensure that each of the Home Nations had their captains on the tour: Karl Mullen, Ivor Preece and Bleddyn Willams were the other captains. He resumed the Scottish captaincy on his return. Peter became a Scottish folk-hero by dropping a goal from the half way line in their 19-0 defeat of Wales in 1951. In all, he won 21 caps between 1949 and 1954. Though Scotland collected four Wooden Spoons in this time, he remained a constant source of inspiration to his colleagues and an outstanding player in the pack.
He made a successful career as a businessman, mainly as a Lloyd's broker. He lives in retirement in a converted pub in Wiltshire.
