The return of football after the war saw Lynn appoint James Henry Robertson as player coach althoigh the season had alreay started before his appointment.
Born in Berwick on Tweed on 22nd March 1913, he captained his school team at Ashington at the age of 10 and went on to play for East Northumberland schoolboys and was a member of their team when they won the English Schools Shield in 1926.
Robertson spent his early career with Welbeck Colliery and had a trial with Notts County in the 1930-31 season then seven years at Bradford Park Avenue before transferring, in February 1938, to Bradford City where he spent the
best part of three seasons scoring 17 goals in 36 league games for the club.
During the war he played for Mansfield for three years and then became player-coach at Billy Walkers' Nottingham Forest.
Arriving at Lynn at the age of 32 he had a wealth of experience spanning some fifteen years and scoring 180 league goals.
Robertson's stay at Lynn was not particularly successful, the club finishing their United Counties League season in tenth place out of thirteen clubs and an average home league attendance of 1,390.
His season was blighted with injuries and player unavailability owing to work commitments.
Robertson scored 17 goals in his season with Lynn, parting company with the club in June 1947 giving the shortage of available housing in Lynn as the reason.
He had spent the season staying in the house of club secretary Mr Len Rush in Kent Road, Gaywood whilst his wife and daughter had remained in Warsop near Mansfield.
