I can help with those: These are rather late war Leitz 7x50 Marine binoculars (beh being the producer code for the Ernst Leitz Wetzlar optical works). According to the serial number, production should have been early in 1944. Overall condition does not seem so good. Nevertheless, if the optics are still ok, no fungus, no chips in lenses and prisms, these binoculars have some value. Maybe 200 Euros on ebay?
The binoculars with Eagle and Swastika and M for Kriegsmarine date from earlier in the war.
I have done some research especially on historical Leitz binoculars, therefore I am able to help rather well in this case.
