Content of Beobachtertasche Fl. 23819

[Hinkle]

Hello,
I am looking for the content of the Beobachter-Navigationstasche Fl. 23819. Beside others it should include:
- aviator ATK 3 fl.nr. 23821
- koppler K 3 fl.nr. 23810
- 1 Sass Luvwinkeltabellen Lvw 4 fl.nr. 23813
- Wegzeilgeraet WZ 2 fl.nr. 23815
- 1 Navigations-Flug-Berichtsblock fl.nr.23830

I was not able to find a picture of any of the items above. Does anybody know how these tools look like?
Thank you.

This stuff belongs to the pre-war Beobachtertasche (1936 ?), will be hard to find the things or pics, I've never seen a complete one.

I was afraid of getting this answer..I am surprised there are even no photos or technical drawings.
