I received the S.E. 5a as a Christmas gift, I have for years concentrated on figures, so I decided as a change to give it a go. I opened the box, that’s when I started going “errrrrrrr”. A, the sprues are marked as Eduard not Ravell. B. There are many alternate parts and no instructions as to which to use on the two versions of the aircraft shown. C. The instruction pages are weird in that parts appear on sub assemblies as if by magic, as they are not mentioned in any previous step. I have attempted to find a pdf from an original Eduard kit and have failed miserably, can anyone help with a useful link please.
