Western Electric 509W 1918 marking on the back of each earphone. The earphone on the left does not have a diaphragm and note the "speaking tube" up top as well as the normal wire hookup on the bottom. The earphone on the right does have a diaphragm under the cap. The "business" on the right is neatly done ... that on the left ... not so.
Any chance 509W headphones are for military use?? |
