In his first full season at Carrow Road, Norwich had one of the most famous FA Cup runs of all time when they reached the semi-finals as a Third Division side. Allcock scored against Tottenham Hotspur in the tie at White Hart Lane.
If he had continued to play as a forward, he would almost certainly have beaten Gavin's record. Allcock also has the record of scoring 37 goals in a calendar season, the highest achieved in any calendar season by a Norwich City player.
