Identify this vintage "Mixer"?? 3/8" Drive

[NKlamerus]

Found this at the goodwill. Could be art? But why go through the trouble of adding a 3/8" drive with a collar?

It wouldn't mount flat to a wall.

Model # is 182C

Looks like a mixer to me

mixer blade of a hand crank butter or ice cream machine.

this etsy seller identifies it that way.

Also a google search (image turned on) of this: "mixer blade of a hand crank ice cream machine" shows a few like this as you scroll around.

And the lack of tightness of those screws is important to good ice cream making.
