@Peter S
My redaction 1935 is without the updates (Deckblätter).
Look in your H.Dv. the update is dated 25. August 1942. Time you can get the H.Dv. with including Deckblätter redaction 1940 and 1942.
The 1942 is original like 1940, only the mistake on “Tafel 1” is different.
Sorry, the manuals have no markings, one only with the name from the owner.
You know H.Dv. 256?
@Kammerjaeger
Yes, the mistake is K98a and K98k.
Curio ;-)
