Vintage MCM Turquoise or Aqua Sunbeam Mixmaster Standup Model 12 MACHINE ONLY.  The beaters do not match, and so they clank. While the motor seems to run OK and is fully adjustable, it isn't optimal. If you can find original or a pair of matching beaters that fit this, then I think it will work. 
This is a bargain basement price -- add to other parts and you're good to go! Or it is simply a great visual for display of this fantastic color! 
Bowls NOT INCLUDED. The bowls are being SOLD SEPARATELY.
