During World War II, Gillick "guested" for home-town Airdrieonians and Rangers.[6][3] At the end of the war in 1945, Struth brought him back to Ibrox.[7] He developed into a forward with excellent ball control and vision and became a feature in the famous post-war Rangers side, forming a partnership on the right wing with Willie Waddell.[4] In his second spell at Rangers, he won one League Championship medal (1946–47), a Scottish Cup in 1947–48 and two League Cup medals (1946–47, 1948–49) in addition to several wartime competitions.[3] By coincidence, the last trophy he lifted was the Glasgow Cup with a win over Clyde in October 1949, the same tournament and opponent the first cup he won with Rangers 16 years earlier.[3]
Gillick left Rangers in 1950 but made a comeback Partick Thistle in August 1951. He played one season with the Jags[8] (managed at that time by his former Rangers teammate Davie Meiklejohn) before retiring to oversee his business interest, a Lanarkshire scrap metal firm. He died on 12 December 1971, aged 56, from undisclosed causes, on the same day as Alan Morton, also a retired Rangers player.[6][4]
