This is a rare example of a pair of Barr & Stroud naval CF41 binoculars, which were part of a batch of 1000 pairs renovated by Avimo Ltd between 1985 and 1988. The renovation included the addition of coated optics and replacing the original Bakelite prism boxes with aluminum alloy ones, making the binoculars about 100 grams heavier.
The only markings on these binoculars are a serial number R/87/AVL 819 etched along the top rim of the right prism box (indicating they were renovated in 1987), and an AP 1900A over 7X on the front of each prism box.
The leather case has an AVIMO metal plate affixed to the inside lid which reads "THESE OPTICS CONFORM TO NAVY SPECIFICATION DWS/O Spec.1 AND HAVE BEEN REPAIRED TO A SERVICEABLE 'NOT NEW' CONDITION" but with a non matching serial number R/87/AVL 498.
As with most of these renovated binoculars the body has been repainted gloss black, and a bright red dot painted on each barrel just below the yellow arrow.
The optical performance of this example is very good, and the 50mm lenses focus well with a bright sharp image,
Both eyepieces can be independently focused, and have 3 built in filters (grey, green & polarising) which are mostly clear, although the grey filter is a little less clear than the others, but still acceptable.
The cosmetic condition is good, and although the original leather case has had extensive repairs it's still serviceable.
These are serious binoculars weighing just under 1.7kgs without the leather case, and 2.4kgs with, so due to high international courier costs these are for UK shipping only.

A pair of WW1 Royal field artillery Bino Prism binoculars by Hunsicker & Alexis of Paris with serial no. S.I.04275 complete with a later leather case stamped 'Dollond London'.
Hunsicker & Alexis were optical supplier and manufacturers for the French Ministry of War but also supplied the British military who prior to WW1 were experiencing a shortage of binoculars.
The optical performance of this example is very good, with independent focusing for each eyepiece giving a clear sharp image.
With only minimal paint loss and still having its original leather neck strap, these binoculars are also in very good cosmetic condition.
Weighing just over 800 grams without the leather case and 1.2kgs with, these are still practical for use today.

This is a pair of genuine Carl Zeiss binoculars which are in very good cosmetic condition, with only some minor paint loss on the bridge stem.
The lenses are clean and give the sharp clear image that is in keeping with the Zeiss brand quality.
Engraved CARL ZEISS JENA, JENOPTEM 8 x 30W, on one side, they have the serial number 4542125 on the opposite.
They have a leather neck strap with a rectangular eyepiece cover, and are housed in a quality professionally stitched leather carry case with shoulder strap.
I have used them on several occasions and the image quality is excellent.
Measuring just over 6" across and weighing 0.5kgs without the case and 0.8kgs with, they are robust yet lightweight enough for most field pursuits.

A fine example of a pair of Dollond 8 x 30 field binoculars serial no 46155 with their original leather case, also impressed with the Dollond name.

Measuring just over 5" in length and weighing 0.5kgs without the case and 0.9kg
