A couple of very interesting images added to the SDASM's Flickr Commons collection today. The description for the side-view of the model in the photo is incorrect, however, the adjacent photo in the collection with a head on view describes the model as, "Model Aerojet; Plastic Space Plane Date: 07/09/1962". The name on the model stand for the side-view describes the model as "Aerospace Plane."
As best as I can glean from the two photos of the model, it appears to be mixed-propulsion, with intakes aft along either side, presumably for the air-breathing portion of flight, plus what appears to possibly be provision for retractable canards on the nose.
This design doesn't ring any bells with me, it may even be a nominal representation of an "Aerospace Plane" concept, but I figure many here may have a better idea (if so, moderators please move to the most appropriate topic).https://www.flickr.com/photos/sdasmarchives/33507549292/https://www.flickr.com/photos/sdasmarchives/33280381880/
