The offered plate is the 1941 edition in the series.  It measures 25 cm or about 10" in diameter.  Reverse has the the double runic symbol above the Allach hallmark.  It also has two mounting holes for rope hanger.  The design on obverse is of the highest quality as expected from Allach.  The condition is flawless; no cracks, chips, or damage of any kind.  I personally obtained this plate from a local estate sale of the WWII veteran who brought it and two others home as souvenirs.  I have no provenance beyond that, but can assure the buyer the plate is 100% authentic.
