The patches Darin showed in post #5 were described by Weitze as being for those who took the A, B or C tests whilst participating on a Wehrertüchtigung course (pre-military training). Patch 2 in Darin's post shows a patch with lightning which Weitze describes as being for Level C of the marine signalling test. Now, I'm looking but I can't find anything in the regulations about these particular patches. We are all familiar with the usual MHJ qualification patches but those in Darin's post are a mystery to me. In 1942 an agreement was reached between the HJ and the Kriegsmarine to provide training for the 'Marine-Wehrfunk' which was designed to provide a pool of boys with training in German navy signals procedures (MHJ Wehrfunker). I'm wondering whether the patches with anchor and lightning were for wear by these boys but I have nothing confirming that.
I'll keep looking but does anyone else have any more info?
