vtg Wearever MicroRave Meal Rack adds second layer to microwave 14.5 x 12 x 3.75

vtg Wearever MicroRave Meal Rack adds second layer to microwave 14.5 x 12 x 3.75 I am not sure this has ever been used. The box is open. The original receipt from 1981 is inside as well as 19 page "Recipe Combinations for the Meal Rack". Recipe booket has dings at corners, box shows some wear. Please note the dimensions -- this is large -- larger than the microwave we currently own (I remember my mother wanted one of these so badly in the 1980s and then never used it. LOL) It does not rotate, a basic stand made specifically for the microwave.
