Need help identifying my Zeiss Jena Marineglas 6x30 binoculars (1 Viewer)

[sophietayl]

Hello all,
I received from my grand father a pair of binoculars.
They are Zeiss Jena
Marineglas 6x30
Serial number is 718118 or 718116
I’ve attached some pictures
I found some info online but none of the pictures I’ve seen so far look exactly like my model!
Thank you heaps in advance for your help and your time!!
Sophie.

sophietayl,
Zeiss produced this 6x30 binocular from 1907 until 1975 (Jena). Originally it was indicated as Silvarem and round 1915 also as "Marineglas".
FOV= 130m/1000m, weight approx. 630 g.

The binocular seems never to have had coated optics so probably pre 1950 or pre 1940..

The serial number puts it into 1916/17.
