He left Hillsborough for non-league Gainsborough Trinity and then with Colchester United, where he was a consistent scorer in their Southern League days.
Curry signed for Colchester before the start of the 1946–47 season and made his debut for them, and scored, just a couple of months before his twenty-eighth birthday in the home match with Gloucester City on 31 August 1946 which they lost 2–3.
In 1949–50 Colchester finished second on goal average to Merthyr Tydfil and won the Southern League Cup, beating Bath City 6–4 on aggregate in the two-legged final.
Curry scored twenty league goals, but was third on the list behind Vic Keeble, who had forty, and Fred Cutting with twenty-one.
He was a captain of the team and led the U's through their momentous FA Cup run of 1947–48, which saw the non-league side reach the Fifth Round, knocking out the giants of Huddersfield Town along the way.
