When I first saw these photos, my first reaction was ..."Well, I'll be a dirty name". I dare say that if I came across these wings for sale, without having seen them in period photos, I would think they were fakes. Why? Because the end result looks "lazy" and unfinished.
The RMA wing appears to be made with thread instead of bullion, which, according to Special Regulation 41, could be considered as correct as it stated wings were to be "embroidered" doesn't say in what, just embroidered. However, how many period wings have you seen that were actually embroidered in thread? Also, the details shown in the second set of photos look like some fakes that I have seen recently...go figure.
