Rick, ask and ye shall receive.
Here is a comparison of an original Juncker Pilot Badge (J2) on the left, and your fake on the right. There are many differences to be seen on both the eagle and the wreath, but the quickest and easiest difference to see is the detail and shape of the tail feathers. On the original, there is virtually no feather fletching to be seen and each feather shape is different. Whereas your badge has a very detailed fletching and very consistent length to the feathers.
Just look around the rest of the eagle, specifically at the exact shape of each feather and you will see many other differences.
