I picked these up from a car boot sale today for £10 and I'm pretty sure they're British naval binoculars. They came with the case and one lens cap missing (sob). Now as hard as I tried I couldn't get good close up shots of it so I'll type out the text by the eyepieces, from top left to bottom right:
BARR & STROUD A. P. No. 1907A
7X C F.42 SERIAL NO. 19633
GLASGOW AND LONDON
BRITISH PATENT BRITISH PATENT
Any help as to origin, value and any other info would be much appreciated!
