"The late Peter Davis was with Argyle as a youth keeper before City and eventually became one of our top referees and football league linesman. One of the best I officiated with. Incidentally, his brother Richard was a former Argyle, Southampton, Bristol City & Barrow professional player before playing for the successful Falmouth Town side 1974-78 Western League Champions, he signed for Bideford Town in 1976 I believe, and managed Plymouth Argyle youth in the '80s."
