Last time we played a team in the third tier of non-league football (1 Viewer)

Has it happened post-war in a competitive match? :thinking about:

I can't think of any examples below Conference level since I've supported the club, ie Sutton (89) and Woking (97).

What level were Kings Lynn playing when they beat us in the 60s?

Plus Torquay and Kidderminster (2009) of course.
