I've recently completed the conversion of an AMT KC-135 into an RAF Airseeker/Rivet Joint.
I used the Combat Conversions resin set which provides new CFM-56 engines, new nose, cheek blisters and the various aerials and sensors that adorn the aircraft. The decals were from the Hannants' Xtradecal range.
Paints were a mixture of Revell and Xtracolour enamels.
Regards,
Rob
