Counter Blender

This picture is from the kitchen at Wildwood, where I often teach. Never much paid attention to it until the other day. It’s a built in blender motor and switch. I was curious so I turned the switch and the motor still works!!! Have no idea if a newer blender would work but I think I am going to give it a try. Kinda cool, although I see limitations. If the motor goes probably impossible to fix. Then again, I have no idea how old it is, but it still works. Any idea when these were made and installed? Any body ever have one They are going to be remodeling the kitchen soon so I am sure it will be pulled out.

If you unscrew this knob there is an attachment for the blender inside.
