Museum Archive: Vintage Len Thompson Northern King 28 UV, 1/2oz Silver / Yellow / Green UV fishing spoon #5568

With a weight of 1/2 oz (14 g), the brass body of this lure is easily identified by the 'NK 28' stamp near the top eyelet. The surface is plated in genuine silver, a manufacturing detail Len Thompson introduced to maintain a high-flash profile in deep water. A rippling diagonal pattern of neon yellow and green covers the silver face, utilizing fluorescent pigments that react under ultraviolet light. First appearing in 1984, the Northern King 28 UV (Product Code 5568) is a dedicated trolling spoon measuring 3 3/4" (9.5 cm) long. This Canadian-manufactured piece is in top-tier condition, rated 5/5, with the silver plating on the hex-patterned back remaining bright and clear. A heavy-duty split ring connects the silver-finished treble hook to the tail.
