_"You really found an outstanding fly fishing item! It's the "Improved Common Sense Dry Fly Box" made by F.W. Klinger & Langbein Co. of Philadelphia, Penn. ca. 1938. K&L Common Sense fly wallets and boxes were a mainstay of the American fly angler for 75 years, but especially in the first half of the 20th century. Yours is the "Rolls Royce" of Common Sense boxes, the "Improved" polished aluminum fly box with twin transparent covers and tweezers. It's a lower cost version of the British-made Wheatley box, and a great item. It was offered alone, and attached to a genuine pigskin fly wallet. In nice shape with tweezers, this box is worth $50-$75 -- but try and buy a better fly box on the market today for that price. You can't.
