These have just come directly from many many years storage and still show the dust and dirt from many decades of improper care. In good working order these are a pair of POWER X 6 binoculars, as often used by Officers in the Trenches. These are maker marked by ROSS of LONDON on the left barrel base plate, and have the date coded 1917 (Loops like NP17). They have covered in at least four large inlaid Broad Arrow markings, as well as two in paint on the barrels. A nice sleepy set over 100 years in age, only a bit of cleaning needed before they are ready to display.
