New parts were introduced into the Erector System in 1958. Building upon the space theme, the (P14A686) Rocket was included in No. 10052 and larger sets. Four variations of this plastic rocket appeared over the next few years—two of them specific to 1958. The earliest version had a white body, blue tail fins, and a red nose cone. Each piece was cast separately and then assembled into the finished rocket. By the end of 1958, a less costly manufacturing technique was used: the entire rocket was cast from a single piece of yellow plastic, with the nose cone painted red. Beginning in 1959 and during most of 1960, the rocket was made from white plastic instead of yellow plastic—with the same red nose cone—creating a third variation of this part. In late 1960 until the end of traditional Erector production in 1962, a fourth variation was introduced when a molded ring was added above the fins.

Now the line was expanded to four sets, and they all came in tubes that were capped with a blue, plastic “nose-cone” that made the container look like a rocket (Nos. 18010, 18020, 18030, and 18040). This nose-cone had a slot so it could serve as a display base for the models. The black plastic display base offered with the set in 1959 was dropped.

CHAPTER 5

Page 205 – Paragraph 2, revised last sentence and added footnote:

The line of these sets was expanded in 1934, but in 1935 the cardboard inner lid parts displays gave way to inner lid labels on most of the sets as Gilbert continued to develop the regular Erector line.
