In 1943 Hole in the Wall Colliery and Peases West Welfare merged to form Crook Colliery Welfare. When the Northern League resumed in 1945, the new club took the place of Crook Town, whose name they adopted in 1949. In 1952–53 they won the Northern League, and the following season they won the FA Amateur Cup again, defeating Bishop Auckland in a second replay in the final. In 1958–59 they won the league and reached the FA Amateur Cup for the third time, winning 3–2 against Barnet. They won the Cup again in 1961–62 with a 4–0 win over Hounslow Town in a replay, and the following season won the Northern League title. A fifth Amateur Cup was won in 1963–64 when they defeated Enfield 2–1, but thereafter the club went into decline. After thirteen seasons of finishing in the top six in the league during the 1950s and early 1960s, the early 1970s saw the club finishing near the bottom of the league. In 1976 they became the first English club side to tour India, when they played six matches there, including a 1–0 defeat to the Indian national side, a match was watched by a crowd of 100,000.
