Nottingham City Transport 431 (12.10.2021)

Having later on found out that one of the Bridgford Bus branded bio-gas Scanias in the form of 403 ended up on the school extra 57X, spares were always going to appear on the route with the Bridgford Bus branded bio-gas Scania of 402 still being off the road too! The one other spare on the 6 came in the form of this 18 plate bio-gas spare, as illustrated here. 431 is seen on Stamford Road with a 6 to Edwalton.
