    Kuban, Narvik, Demjansk possibly Deumer

    The first time this topic was ignored, but I want to hear your opinion after updating the forum.

    Of course, with 100% probability it is impossible to say that Deumer did it, but the plate was used alone in the Krim and the Kuban and defects were left with one tool. Probably a rolling machine.
    1. Steel Deumer.

      2. Zinc Deumer. NOT on all plates this defect is observed, but I would associate it with the material.

        3. Kuban is an unknown producer.

          It’s hard to say from this image, but if enlarged.
          Increased:
          1. Steel Doymer.
          3. Kuban is an unknown producer.

          Characteristic marks appear. Parallel indicated the direction of movement of the workpiece, and the arrow marks the marks of the die cutting.

            The workpiece probably shifted, so some distinctly visible lines, some somewhere higher, then lower, but their slope is the same.

              I made an overlay of one plate (added transparency) to the other with a little shift, so that it is clear that they are identical.

                Narvik Deumer has similar bands.

                  and Demjansk
                  Compared to Narvik.
                  The different inclination to the Krim / Kuban and Narvik / Demyansk can be explained by the different location under the cutting of the plate to save material.

                    The paper is similar in structure.

                    And the color is different due to different colors. Unfortunately, there is no way to compare in hand.

                        Lets start by complimenting you on your research Vladimir.
                        Very impressive.

                        The Krim shield you've shown is attributed to Deumer there is however no definite proof that these shield were made by Deumer. Reason for attributing these shields to Deumer are mainly because of the sample boards.
                        Anyway, for now it safe to assume that these shields were made by Deumer.

                        The backing plate on all these shields show indeed similar marks. It is therefor safe to say that these backing plates are:
                        - made by the same manufacturer, and/or
                        - made with the same tool.

                        The Krim shield type and the Narvik shield type were already attributed to Deumer. The Kuban however was attributed to an unknown maker. Going through my own collection of shields I also have these markings on the backing plates on all of the above 3 type of shields (Krim, Narvik, Kuban).
                        I would say it is reasonable that we from now attribute the Kuban shield to the same maker as the Krim and Narvik shield which is most likely Deumer.

                        I have a problem with the Demjansk shield you've shown. The most encountered backing plate on this type is a copper colored iron backing plate. On the backing of the shield in my own collection I cannot see this pattern. Also going through my collection of pictures it is difficult to see this pattern on most of these shields. So, for me, I think it is too early to also attribute this type of shield also to Deumer.

                        Otherwise excellent research work and thanks for sharing this with us Vladimir.

                          Hi Pascal. Thank you for your answer. Is it possible to compare this Narvik and Demjansk? The size of the plates is identical? Distance under the hole under the prongs?

                            Here are the measurements of the backplates of both shields.

                              Thank you, Pascal. Does anyone have similar shields? Can measure the same distance?
