Battle Of Britain Class Locomotive Nameplate Crest showing the RAF Badge. Vitreous enamel centre with gunmetal frame. A number of B-O-B locos carried this generic RAF Crest, primarily the 'Airfields', 'Fighter Aircraft' and some 'Personalities'. However, the 'Squadrons' were certainly the exception as these carried crests with the squadron insignia. Ex loco condition throughout.
