Noel Baxendale recalls this public information film starring a young Patsy Palmer, better known for her appearances in 'Eastenders'. A group of youths get off Grey Green 493 (GND493N), which was previously Greater Manchester Transport 7433. it's a 1974 Daimler Fleetline with Northern Counties bodywork:

The bus station has two London Transport buses parked up. Jon Price adds: “the only place I can think of where United Counties and Invictaway services may have met (except Victoria) with LT buses parked in the background is the bus station at Aldgate Minories and from memory the stands pictured look like those at Aldgate.”
