Rare prism deviators of the French Marine Nationale, model nr. 1933. These prisms used to be mounted on the Huet binoculars of the French marine as can be seen in the last photo which I downloaded from the internet. That binocular is of course not a part of this sale. They can be put on both sides of the binoculars, but in this case the left one still looks less used. So maybe not always were both of them used together. The prisms are still in their original carrying case,. This leather case is around 22 x 10 x 9 cm. Please take a good look at the photo's for a good impression. Will be sent carefully wrapped, insured and with tracking code to the winning bidder.
