Just in today!! A field grade ranking tunic for a Luftwaffe Signals Official! This is the first such tunic I have ever seen. This particular tunic is a private purchase piece(as are all of the Officer Level Officials tunics I have ever handled). The upper pocket flaps are sewn down at the corners. From everything that I have read, these men worked in Research and Development for "state of the art" transmission equipment, as well as other very specialized roles. Some examples could be developing, perfecting, and operation of navigation systems on remote controlled weapons, radar, codes, and etc. If anyone has any thing to add, I would be most appreciative!! I look forward to reading your comments.
