"this model is a bit of a mix-up"

Theres no such thing as 100% historical accuracy. In field modifactions where/are commonplace for all soldiers. How many sqauddies today buy their own boots because the kit issue is kack ?.  Vehicles even more than uniforms often get the comfort zone treatment.    

If you consider a typical scenario of that period - your're retreating from the Red Army  would your prime concern be saving your a**e or worrying if your uniform had the right insigina ?

Nazi swatikas are only illegal in Germany if used to promote right-wing material. Kit modellers have been able to purchase and use aftermarket decals for years. Look in Finescale Modeller and you'll see german and former soviet bloc companys selling them. So theres no legal issues here.

Theres a big hoo-hah here in the UK about a bank built in the 1920/30's  which has swasitikas on the floor. When this built the symbol meant good luck. Now some groups want these removed because it might hurt someones feelings.   Just another silly example of how P.C. we've got.  

Yet last year when around 16000 watched  a WW2 german plane complete with swastiki beating up shoreham airfield in a great pyro display. You'd didn't see protesters complaining about the insignia. But I reckon if you censored this, then you'd hear complaints because  you're removing a core part of it's historical context.  

BTW - Farnbrough airshow is on again this year :)

Pinky - you left the lens cap of your mind on again.
