I remember "models" like these. My childhood dentist had some navy planes in his office, and my uncle, a salesman for Learjet and Cessna, had several of them.
Uncle Tommy gave my hyperactive kid brother a "spare" learjet model. My brother treated it like a toy and I think it lasted a week. It was made of some kind of brittle composition material. I remember how lame it looked after my mother glued the tail back on with Duco cement; missing bits of the glossy shell showed the sawdust / cement casting material underneath.
I much preferred the plastic models that Bob refers to!
