A little game for the weekend. Weird Zeiss Binoculars

[Mikedenmark]

I have been to the Archives here in Copenhagen and here are some photo´s I found. Sent from Zeiss to the danish army, around 1938.

There isn´t much in the papers about what we see here. So I thought it was worth a try to make this into a little game.
What is different about these 3 binoculars? One is easy, I admit. Which one of them might that be?
And should anyone be able to shed light on the numbers below the photos, please tell us all. They are all Zeiss factory Photo´s.

A couple of notes as well:
The 10x80 80 degree binocular was available in 1936. A special version of this was made in 7x60. Only difference to the 10x80 was supposed to be the outer objective tube size.
I have never heard about that one before.
Designation for the 10x80 was Bibefesche. Binokuläre Beobachtungsfernrohr, mit Schräge Einblick. Anyone can see that MUST be Bibefesche'

Update
I should have googled 7x60 Zeiss before I wrote this. This is hot the 7x60 looks like. German navy markings to top it.

Seems no-one want´s to bid in on these.
Maybe the photo´s cannot be sen ?

The septar is unusual by having cylindrical outer ends on the objective barrels.

The 8x60 has loops for the carrying strap on the sides. All other 8x60 I have seen has them somewhere else. Or none at all.

The old 8x60 has objective cover straps riveted to the bridge. A 3rd. not seen before detail.
Besides the shape of the main body looks as if it was designed cylindrical, where all others I have seen, are partly conical. I admit, it can be due to the angle of the camera that took the photo.
