Today I received this very nice summer jacket that had no date. I don't think I've seen this type before. It's constructed similar to a 1960s Sandfarbe jacket, and of similar material, but it doesn't appear to be a Sandfarbe jaket dyed gray. It has a very interesting feature which is related to the shoulder straps. I'll explain that in a sec. Here's the overview picture:
The rank is the 1950s pointed type, made from the same material as the jacket:
The very interesting feature is the reinforced "pass through" gap between the top seam between arm and shoulder. The bottom of the rank goes into this gap and a flexible metal strap is slipped through to prevent it from sliding out:
Does anybody know what this is for sure? There is no date on the label. My only guess is the "Truppenversuch für leichte Sommerbekleidung" shown on page 40 of Kunstwadl's book.
