Glencoe is to be applauded for saving some classic models. The Convair Observation Satellite, originally produced by Strombecker in the mid-1950s, fed that time periods' modelers' hunger for spacecraft kits. Thankfully, Glencoe was able to acquire the original molds to reissue the kit starting in the 1990s. This is a challenging kit to build, and will require patience. The fit is often poor (not Glencoe's fault), so expect to work with the parts a bit. Blending the seams will require good technique. If you are a Space Age history buff, the effort will be well worth it.
