Klaus, Görtz also mentions an Allgemeine Heeresmitteilung dated 22nd Nov. 1935, as well as the Heeres-Verordnungsblatt of 15th July 1941 on the subject.
Reckendorf cites the fist Allgemeine Heeresmitteilung dated 9th Nov. 1935 concerning the lanyard and the Oberkommando Order dated 5th July 1941, but also adds that "There were a number of different types of lanyard for the Models P 08 and P 38".
Could you therefore explain the basis of the assertion that the lanyard depicted above is the official version as mentioned in these Heeresmitteilungen?
