Jeff, the cufflink pictures from the 1993 Meyer and Schild secondary source reference that I posted do not,unfortunately, have any checkable primary source attribution given to them by the authors. (Some other items in their book do have a checkable source, e.g., the photos are taken from the 1938 and 1939 applied arts and handicraft exhibition catalogs held at the House of German Art in Munich.) However, the cufflinks pictured by and described by the authors in the post-war photos I posted are attributed to a private owner. The authors further imply that the links were a Julfest gift from RFSS, the date 21.12.39 being engraved on the reverse. They do appear to be of higher quality than the fakes we have all seen over the years.
