First pattern Luftwaffe decal on an M35. These decals are called "droop tail" referring the down-turned tail. In addition, the upper foot on droop tail decals differ. This example is called a "straight leg" where the left leg is almost perpendicular to the eagle’s body (photo courtesy Anders Lehrman).
Green Luftwaffe decal produced by Huber Jordan & Körner on an M42 NS. This is a "reissue" decal that was often used on helmets requiring new decals after being repainted. While difficult to tell from this photo, there is another LW decal under the last coat of paint that has crackled around and partly inside the green replacement decal.
