This is a very nice kit from Aurora's later, improved efforts of the late 1960s/early 1970s. Aurora knew that the old 1950s molds were outclassed by the late 60s and cut a new series of molds including several ships, helos and subs. The result was high mold quality and very good details, as in this kit. Quality was so good that this was one of the few Aurora kits reissued by Monogram when the bought the Aurora molds.
