Davies was one of very few Welsh players to represent his country on either side of the Second World War.
His first international game was against Scotland as part of the 1939 Home Nations Championship under the captaincy of Wilf Wooller.
Wales beat Scotland 11–3, and Davies was reselected for the very next match at Ravenhill Stadium in Belfast against Ireland.
Wales were victorious, but with the outbreak of World War II, this was the last match either team would play for eight years.
When international rugby was re-introduced, Davies, now playing for Llanelli, was one of only two capped players to be chosen for the first Welsh match in the 1947 Five Nations Championship against England; the other being captain Haydn Tanner.
