Eric,
There is a very slight possibility that they might be just crappy private purchase examples, but they don't belong on an issue Bluse anyway. A Bluse from a non-Bavarian unit would nearly always have the shoulder straps whip stitched on to the shoulder, not into the shoulder seam. I would take these off, sew the holes back up and then add proper examples. If you want to go infantry, you would be looking for a pair from IR.78, 73, 74, 79,164, 77, 92 or FAR 26, 62, 10, 46. Of course, there are many other possibilities. If you need some help, let me know.
