Mom's mixer is 20-30 years old. It says: Service 2366 120 Vac 60 Hz 3 amps 275 watts Listed 564A Sunbeam Mixmaster… Here's Mom's exact message: The pusher thingie that you use to take the mixer part off so you can use it as a hand mixer came off and fell down inside...we have taken the bottom off and retrieved it..but can't seem to reattach it..
