'Melbourne Ten' by Brian J Rapier , published by Air Museum Publications (York) Ltd in 1982 , ISBN 0-9507326-1-3 and rare as hens teeth to put it politely !
Chapter 5 : Hamburg and the Hundred Ops , page 47 has a photo of S/L Debenham and his air and ground crews captioned 'with the much censored X-Ray' . There is a photograph of Halifax BB324/ZA-X on page 49 and in the text it states 'Sergeant Pinkerton flying ZA-X-Ray , BB324 , failed to return from Mulheim , one aircraft cancelled at take off and two returned early from this , a 20 aircraft raid . Squadron Leader Debenham often flew this aircraft and is in the left hand seat of this photogrpaph of BB324 flying on 'one' .'
There may well be other references to S/L Debenham too elsewhere in the book ? I also found that Debenham was awarded the DFC ; Debenham . Archibald Ian Scott . SL . (70167) . RAFVR . 10 Sqn : London Gazette ; 12 November 1943 : 4972 .
