Yup top one VC10 and as it as a fin tank I would say a C1K, none tanker variant didn’t have dispense part if memory serves me correctly or the totaliser, as an ex VC10 engineer… nice

I don’t think it is a C1K as those don’t have a HDU. VC10 tankers with both a fin tank and a HDU are either K3s or K4s, and seeing as the K3s are still around it must be from a K4. Possibilities are:
– ZD230, scrapped at St. Athan April 2006
– ZD235, scrapped at St. Athan January 2004
– ZD240, scrapped at St. Athan 2006
– ZD242, scrapped at Boscombe Down February 2011
