For your consideration, here is a 1958 Project Vanguard Satellite Model Kit No. 515-100 Box, Instruction Sheet and 2 Parts Only, from Hawk. I just have the box, instruction sheet and a couple of plastic parts.

The box has some wear on it, mostly on the corners. There is a crease to the left of the HAWK on the front that extends 1 3/8 inches from the edge. There is another small crease that extends in 5/8's of an inch, to the right of the satellite on the front. The instruction sheet and 2 parts are in nice shape. Item pictured is the actual item up for sale and comes from a non-smoking household. (142.100w-.12of)

[Thanks for looking!]
