Looking good Ron. Looks battle worn and weary, without the usual effects being too articulated. The stowage front and back, is excellent and the colours are tied together very realistically.
Looking at colour photographs from the period, the colouring would be identical and if thats what you´re out after, you should be very happy. But the "artsy" part of me thinks a splash of colour, like an identification panel, would break it up a bit and add contrast. Nice one.
