This blender is from the Late 1970s to early 1980s.
The center of the cover is removed to use the Sauce and Salad Dressing Maker into the cover.
The center of the cap also is marked for 1 and 2 ounces.
Includes the Blender Cookbook, Sauce and Salad Dressing Maker cookbook. The blender use and car instructions are in the blender Cookbook.
It is in good used condition. The color may be a little yellowed because of it's age. I rarely used it and has spent most of its time in the cupboard. It has been tested and works on all 14 speeds. The cookbooks are a little discolored because of their age and some stains.
