Hello Mike,
Please, listen the voice of the wisdom of RAG III and did you think that I am a little boy
I don't think.
The SNIPE image is before correction of art work and for the SALAMANDER, of course it never see the "combat" as on the image, also it was possible that this day.... he has this fin.....

, as a lot of the 160 SALAMANDER used after war.... it is "la licence arstistique"

I don't know how translate this in english.
Don't worry Mike, in the kit, you will have both sorts of ailerons and both sorts of fins, it would be possible to built good or wrong SNIPE or SALAMANDER.
About Barker markings, it was difficult for me to do an other choice, his "dogfight" was so great, that it was a sort of "hommage" and

as compensation, you will find on the PE part, the specific "sight" of Barker.
I hope ( I know ) that some decals companies are interested to produce decals for these...
