A standard Luftwaffe officer visor cap badged with the insignia of an officer of Transport Gruppe Speer. The owner was attached to a Luftwaffe unit. I have seen this cap badged with insignia that is all metal, hand embhroidered and a combination of both. Uniform regulations ofr the Speer units has not been widely studied up to this point in time. Existing examples and period photographs show a wide array of uniform and headwear variation.
