What are you telling me with that Google link?
There was no JG 52 'Pik As'. I am in contact with surviving members of JG 53. My Flight Sim squadron for years has been JG53, I ran a web page dedicated to JG53 for years (closed last year). Just buy Prein's JG 53 series, there's plenty of pictures.
Here's a link to Bernd Barbas'
Jagdgeschwader 52 site. He is authoring the squadrons 'official history'. You can purchase volume 1 from his site.
If you are using the 'web' as a source then you will run into inaccuracies. If you are saying you don't care about inaccuracies and will go with whatever Google turns up then so be it. You will still be as incorrect as the image of the G-14 you posted.
YMMV
EDIT:
Also, that wings palette website is full of inaccurate profiles. All that website is is a warehouse of profiles that can be found many places on the web. That site does not respect copyrights either and steals images/works from others. That site my be useful as a guide, or reference (I wouldn't use it) but using it a a primary source is laughable.
My G-14 template should be finished by the week end. My references for the skin I will chose will be from books. If you don't wish to buy books just to do AH skins then a trip to the local library would be my first choice over the web.
