1972-75 Equipment Sets
Some of the equipment sets released in 1972 continued in the line right up to 1975. These sets were initially released in traditional window boxes with blue or yellow borders. The style of the larger yellow bordered boxes changed in 1973 to a box with a cellophane window and the contents on a pull-out tray instead of the earlier card. Some of the blue bordered sets (Missile Recovery, Radiation Detection, Hurricane Spotter, and Volcano Jumper) were released in orange window boxes with the contents under a bubble sealed to a card back.
