I came across this thread in a web search and thought I would add a reply, be it rather late in the day., this might answer some questions and help others who may come on this.
The blc 7x50 set is popularly known as a "Gas Mask" set made by ZEiss. It is a navy binocular and is of excellent quality, I have five of this type.
The repair shop in Glasgow sadly closed in 2016 as the gentleman who ran it (Dougie Biggart) passed away. Dougie was a gentleman no other words I would use.
The gentleman who mentioned "dienstglas", this refers to a German Army binocular, " service glass", unlike the "Gas Mask" set and all Navy sets they did not have coated lens which enhanced light transmission.
The "Benutzer" ( a popular name for these , it simply means "user" ) / rain guard is a mid-war type bakelite, it should secure to a small collar on the set, if this is lost I have a few spares, although I am not sure if the owner will see this.
Servicing them I know a gent in Cowdenbeath who can do work on binoculars, he can be found on Facebook under the name "Bino Bros."
The pop-in filters usually green , red, or blue, ( only two sets supplied) are more than often lost, Glasgow-made Barr and Stroud's sets were better in this area having a built in filter system.
I am not sure if the DeInstg eagle and M are period WW2 markings, have not seen this before.
Attached are some photos of GM sets, and some navy binocular, army dienstglas.
