Nazi insignia identification?

Attachment 67094Attachment 67093I have these Nazi insignia/badges which were brought home from the continent by a British soldier (Essex Rgt?) at the end off the war and then given to my father a few years later. As can be seen some of the cloth badges have never been sown on a uniform and this is because they were "liberated" from a German army supply depot, so are unissued. I wondered if these items can be identified as to which unit and part of the German armed forces they relate, please. Any information would be appreciated, please. I would also be interested as to how common/rare they are today, please, but they are not for sale.

Thank-you for any help that any-one is able to offer.

I can't offer much, but I believe that the edge piping on two in the first picture identifies corps or service. The ones with the silver edge only ribbon is a rank indicator - Unteroffizier or Feldwebel, I think. I believe the one with all silver ribbon on it is a junior officer, but there might have been pips there to indicate a higher rank. The middle top piece in the second picture is collar tab - white I think is infantry.

Off the top of my head i think the yellow piping is Signals, red is artillery and the orange is engineers.

Thank-you chaps for the info. Any further help from any-one else would be much appreciated.
