This is a tough one. I agree that the fittings do not appear to be the "Dachau" type. Are they magnetic? As to the blade, I would not find it impossible for "Luneschloss" or any other maker to make a blade to custom order, including one with the SS motto. The blade, if authentic, may have been added to an existing sword. That is, the blade itself may have been the presentation piece and not the entire sword. The date on the dedication is getting a little late in the period for a degen purchase, although such could have occurred. The etch may provide clues. Is it crisp and clean, especially along the edges?
