This original Flying Sub cast was a safety recast and meant to be molded as they needed Flying Subs. The actual molds of many models were tossed and a safety cast was kept instead. This came from Greg Jein and is fiber glass with plastic fins measures 9 1/2 x 9 inches. Its been in my collection for 20 years.
