Butter Cup Churn-Mixer
 

The Butter Cup churn was made to fit on any type of fruit jar.  You will  notice the two different types of tops.  The one on the left has a cast top marked with the Buttercup Churn-Mixer and the patent date of June 30, 1930 on the opposite side of the lid.  The second on the right has a jar type lid with The Pyle Roy Mixer Co, Inc. Greenfield Missouri.  The value of these would be in the 195.00 range.
