Dad's Army: Lost Episodes

Walker is called up the Army, so Mainwaring tries to have him excused from service so that provisions of black-market goods are maintained.

When he's told he can make a member of the platoon a corporal, Mainwaring instigates a competition between Frazer and Jones to see who deserves the promotion.

Tipped off by Frazer and Godfrey, Mainwaring and Wilson investigate a house from where they believe someone may have been signalling to enemy aircraft.
