Thanks very much chaps ! Forgot to mention, for Lewis' benefit, the control surface ribs are a bit prominent, so they've all been sanded down to a more realistic level.
Thanks David and Jay. The gunsight shouldn't be too hard - a bit of cutting, bit of sanding, bit of drilling, make two transparent lenses, some Kristal Kleer, some paint, and voila!
Oh b*ll*cks, I forgot - it's small and my fingers are big !!
It nearly did! So I glued it in place in the cockpit after the initial work, and just have to do the detail painting and fit the twin screens. Pics tomorrow, with a bit of luck.
