Ray Prosser played for Pontypool and earned 22 caps as a prop for Wales between 1956 and 1961. He was late getting his first cap but, thereafter, established himself in the Welsh jersey and was ever-present during the 1958 campaign. He retained his place, too through the 1959 season and did enough to be picked for the Lions tour of Australasia.
