Great care is needed in this area to avoid frauds.
I know of the FHH presentations to Lutze and Russo; the Naval Honour dagger casings; the HJ Leader casings; and the presentation RAD Leader casings. I have personally not seen an original case for the SA/SS Honour dagger. One off presentation casings do exist, e.g., the Sepp Dietrich LAH presentation sword casing. .
Here is an early 20th century knife box that I fitted out to accept an SA honour dagger. So, great care is needed to determine originality.
