Leyland Atlantean LA1285 could've been one of the last 70's buses to be withdrawn or some of the Leyland Leopard Y-types from Motherwell that were exported to Cuba.
Last 80s bus would've been an AH Volvo Citybus. Unsure of the fleet no.
Yeah , g reg city buses lasted till 2009 , though G was 1989 or 1990 maybe ?
Leyland Atlantean , were the last ones retired the 1980s ones?
