Zeiss 'blc' 7x50 U-boat binoculars

A very nice pair of Zeiss 'blc' 7x50 fixed-focus U-boat binoculars, in completely original condition. Each U-boat would have carried a complement of 10 of these binoculars for use on watch duties whilst surfaced. 
 
Finished in the typical KM shade of yellow/green, this particular set retains the vast majority of the original factory-applied paint, as well as all of the period black rubber armour. The latter is in excellent condition, with very little if any cracking, and is one of the best surviving sets of rubber armour we've ever seen on a pair of these binoculars!
 
The optics, whilst still somewhat usable, would certainly benefit from an internal clean to return them to a fully serviceable state, if desired. This is due to some dullness in the image produced, likely also as a result of wear to the objective lens coatings - a common issue with the seemingly less durable rose coloured coating material that was chosen for use later in the war. Both sides remain in collimation.
 
Overall, a pair which still remains as a superb, displayable example of a highly prized and iconic artefact from the infamous U-boat arm of the Kriegsmarine naval forces!
