It is easy to forget that Scunthorpe is actually a relatively small town in terms of Football League status - 82,000 population. It is much smaller than many of the towns currently in the National League, so a return to the FL is going to be very hard.
Since there have been four tiers, Southport's 3 wins in the 1976/77 season seems to be the record - but they still finished six points ahead of Workington which was the year they only won 4.
Others with only 4 wins were Bradford (Park Avenue) in 1967/68 and Doncaster in 1997/98.
