Nice detail shot Andy. I notice that there isn't a 'dome' for the radio altimeter (often mistaken for a beacon), as fitted to the USAF F-86s. I presume this would be the same on RAF Sabres ?
George, if you can't find any Milliput, let me know, and I'll send you a pack, which should last a few years. It would probably arrive too late for this model, but you'd have it for future projects - one of the best, most versatile modelling products I've ever used.
