Proper Orientation of the JG 3 "Udet" Insignia?

[pstrany]

Hi;

attached is an image of the insignia of JG 3, "Udet" (image source is the Wikipedia page on JG3.)

I dimly recall a long-past discussion where it was asserted that the emblem was always painted with the "U" to the fore, regardless of which side of the aircraft it was painted on. Is this the case, or was the insignia orientation the same on both sides of the aircraft?

Thanks!

Paul
