The badge on the right raises only 2 conserns for me: 1) the finish; Both on the eagle and on the wreath 2) the pin catch; while it follows the correct style, it is not quite right. I only have 1 GWL flight badge (pilot) but the one on the left matches it in every way, including the catch. I would only expect to see variation in the rivets and maker-mark (i.e. the intensity of the break in the ring) If I were looking for a GWL pilot, the one on the right would not be for me. I would only consider, in this case, the text-book one. These are only my opinions. To further analyse the example on the right, you should also check dimensions in case it's a good casting using an original as a mold. It could well be an original that may have been corroded, then cleaned up and re-finished. Rich
