I am pleased to stand corrected about the desiccant capsule which escaped me
, so the one with the "flying pencil" should be a G-5/AS after all (I think it should be time that a clear diagram of the pressurized version with Erla hood should appear somewhere - if it has not already - since all the ones I've seen so far shows only how it was with a standard three-piece cockpit. Also an explaination of the presumably "fake" airscoop would be interesting).
If this goes for the photo I sent, the same should apply for the other aircraft shown in the other two images, but we are then having the same problem: did they were two different aircraft or the same shown at different times (remember the different badge in the same position and no signs of overpainting)?
Thanks to the welcome intervention of Jochen I'm glad that the "white bands" on the wings can be safely dismissed. Now the colour of the "double chevron" and the spiral rest to be assessed.
