4078 Cardigan Castle is carrying a 84A shed plate so that dates it to after September 1963 when Laira was re-coded, yet this loco was stored at Laira and then re-instated to St Philips Marsh in April 1963 only to be stored again in September (dates vary - the SLS quote Sept 29th) so I guess it retained its Laira shed plate throughout this period. It was withdrawn on 3rd October.
