Good used condition Barr and Stroud Binoculars – selling on behalf of my father in-law.
They are in working order however the internal filter system on the right hand lens appears to be stuck.  
There is also slight scratching to the left hand lens.
If you have any questions please ask and I will try to answer them.
Comes with original case and binocular strap.
Manufacturer/Model: Barr & Stroud 7X CF41, 7 X 50
Field of View: est. 7 deg = 123 m/1,000 m; APFOV 49 deg
Weight: 1570 gr
Exit Pupil: 7.14 mm
Serial #/Year of Manufacture: 84497 = manufactured in London (lenses are not coated)
Notes: The Barr & Stroud CF41 was the standard British naval binocular during WWII entering service in 1935 as Admiralty Pattern 1900A and continued to be used as recently as the Falklands War, 1982
The CF41 was derived from the civilian CF30 model and differs primarily in having an internal filter system. It is also considerably heavier having watertight glands on all moving joints (Barr & Stroud Booklet C.50) and unlike the CF30 could be filled with dry air to prevent condensation and fungus. Contrary to popular belief there is no evidence that the CF41 was ever nitrogen filled. During servicing a hand pump desiccator, a 25 kg apparatus which looked like bicycle tire pump, was attached to the desiccator connections, and the air inside the binocular was hand pumped from the binocular into the apparatus to a silica gel filled desiccator chamber which dried the air prior to its being pumped back into the binocular.
