This model is built by the #0521 Space Center Erector Set of 2005 pictured here. Like all “Special Edition” sets, its 688 parts including screws, nuts and washers builds just this model.
The rocket and capsule is about 25 inches high. The entire model from the base of the gantry to tip of the crane is just under 30 inches. (Note Larry’s Walking Giant in the background.)
