KBB/S - Unknown name (Special)

Silver insert in transparent body with blue markings, blue nose and blue tail, silver scale pattern on belly. This lure is illustrated in the book Heddon Plastic Collectibles (1st edition) by Masami Takeyama and Tatsuya Kumada and is identified as color code KBB/S, the /S meaning it was a special order color.

However, this lure is pictured in the Smith 1984 catalog with others Dying Flutters, all having a metallic insert, some of which are gold. Those with a gold insert are listed as /G while those with a silver insert are listed as /S so it seems more likely that the "S" doesn't mean "special" but "silver." (See color code KYG/G)
