Vintage Barr & Stroud 7X CF41 Binoculars & Case

$350

Vintage pair of 1940 WWII Barr & Stroud 7X CF41, 7 X 50 binoculars and case. Manufactured in London / Glasgow. 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. This pair is in good condition with some paint loss, dry rubber rings. Optics are blurred on one side and spotted on the other. Set is marked and comes with the original leather case. Case measures 10.5” x 8” x 4”

From the internet: 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.
