In 1939 the winery purchased a vineyard in Rostrevor and in 1949 another property at Magill. Ronald Martin died in a car accident in 1950; in 1958 Michael Auld was managing director and John Kilgour the winemaker. By this time, the original vineyard no longer existed, but was thought to be where the Stonyfell Quarry offices stood.
