1937-38 saw the club enter the South East Lancashire Amateur League where it made an immediate impact winning the Challenge Cup that season then both the Challenge Cup and Challenge Shield the following year.

Membership cost 3/6. Youths 14-18 years 2/6. Ladies 2/-. Admission charges 5d. Ladies & Boys 2d. 2d for Reserve games.
