Sadly, you would have to do that every year because the fakes just continue to get better and better. And once these fakes are shown, the fakers would immediately change all the little "red flags" that are pointed out and then you have a new set of fakes to have to write about
The best advice I coudl give is to continue to study the originals, and use all the information shown in the Para book and forums to analyze an item. Especially the dimensions, that would have eliminated this fake immediately if they had been taken and compared with the Para book. But even without these, you guys were noticing many little red flags and that is awesome! I know it is sometimes tempting to overlook a red flag or two if the rest of the badge looks good (I do it myself on occassion). But when you start racking up multiple red flags, then you have to sit back and really analyse what you are looking at because 99% of the time it will be a good fake! Here we racked up many flags (poor obverse detail, rivets that are close but not exactly correct, weird catch (both in thickness and silver-color metal), poor maker mark that looks cast rather than struck in, pin end not correct, no eagle flaw, etc.). If you add in the smaller dimensions, the overall picture should immediately reveal you are just looking at a well made fake.
