This is a 1970's GAF Model K 3D View Master in silver. According to research, this color is difficult to find as it was only sold at Disney's Epcot. I have run wheels through it and it works perfectly. The silver plastic was done in a metallic fashion to give it a swirly look. However, there is some scuffing and wear to the finish. Please see photos. The final 2 have some close ups of particular panels.
