Just got this from a garage sale, I searched on amazon, ebay and google for more like of this pair of binoculars but all I could find was the add of it from between 1902 and 1909, which makes me think that it is from this same time period. Apparently it was used by US signal corps. Please if someone ould help me with any informtion on it mainly what it is made of andif it is woth anything. Thank you!
