Single piece moulded black rubber frame that is essentially the same as that used in the USAAF B-8. Fitted with a clear plastic/celluloid filter (lens) and a simple elastic strap. The frame, which has reference details moulded into it, is in good flexible condition but would benefit from a quick clean. The strap is soiled but retains elasticity, there is corrosion on the metal parts. The lens has minor scuffing/scratches but is generally good. Unknown origin but probably American and they make a good B-8 substitute. Stock code G25808.
