I have to agree that this piece looks perfectly legitimate from the front. Based on the description, I would have to go along with the theory that it is an original piece that was unfinished and then "completed" by someone who didn't have much of an idea of what they were trying to do. Anything is possilbe, but I would not count this piece out as being completely fake until I blacklighted it. I have never seen a repro M15 Flieger enlisted strap. I have seen tons of the "simplified" M07/10 unpiped examples. Fortunately, they are all the same and rather poorly made with crappy hand sewn button holes, off-color feldgrau wool and red insignia made from modern thread that melts. I have never discovered exactly where they are coming from. This version is part of a whole series of fakes (mostly cyphered regimental straps and examples with letters, like "LM, SM, etc.") I have seen some of these in the most comprehensive collections, especially the "L" Luftshiffer examples. They have been around for at least twenty years. There are other fakes that are much better and would fool all but the most advanced collector. Regards, Chip P.S. Dante, your red straps with the black "2" are not German military examples in my opinion. I would think they are from some other European country. As far as I know, no German strap ever had black unit numbers (with the exception of some special wartime artillery units).
