Yes, I'm aware that the hilt is not the Dachau type. However, if you go to page 474 in Wittmann's SS book you read where Paul Dinger made blades for other makers on a subcontractor basis. Since blademaking ceased in Solingen after 1940 (on production line basis) Paul Dinger continued to make blades at the Dachau forge.
The runes button attached to the pommel nut was apparently not a common practice but done on request by the owner. There were several other example I had come across in publications or catalogs over the years but I don't remember which and where. I was referring to the swirl pattern of the knurling on that pommel nut. The usual is the straight radial pattern.
