Tim ; I do have the metal collar car insignia that I got from my Grandfather who served as a Kraftfahrer in WW I . I posted a lot of my Kraftfahrer stuff a while back on the wehrmacht -awards , "Imperial Uniforms and Headgear " forum . You can go back on that forum to page 4 and find the following : " K " -for Kraftfahrer Korps " , dated 01-16-2007 , and "Kraftfahrer Visor Cap " ,dated 01-09-2007 ; and " Kraftfahrer-Staffel " armband " ,dated 01-30-2007 . Go and take a look ,--I promise you will find it interesting ! You also will see a photo of my Grandfather in his WW I Infantry tunic. Bernd .
