Thanks for the replies everyone!

Very nice of you to post that profile, Darnsarf – but notice it’s just LE/DG, without the edges. Looks like the illustrator got nervous! The thoughts of DaveF68 are basically the same as my own, and so far DE seems the logical choice for those edges. It`s just so very “un-RAF”!

I `ve attached a pic of the actual Gladiator concerned, saved in Word. Not sure how that will turn out, but hopefully you can make out the color scheme…

BTW my guess for the roundels is pre-war/bright coloured ones on fuse and bottom wings and none on the upper wing – unless somebody has a picture of a camouflaged pre-war Gladiator with roundels on the top wing!
