WW11 binoculars unnown origins from England

would like one of my military expert frinds out there to help my out in getting more info on these. My mom gave these to me at the same time she gave me the hood ornament. What she can remember of these is that her dad (might have picked them up) right after the war ended at one of the numerous army/navy surplus sales in England. She said the other day, she thought that they might have been German, but in pict#3 u ca see thats not stamped in German. They have been in the family since (probably) 1946-48 so im not looking to get rid of them, just wanted to tell her(& know myself) more about them. Thank you Mikie
