Wow -- what a neat item! This is a Swing-A-Way brand ice crusher that looks new!
The plastic ice container (bottom) is black, top (crusher) is white with silver color metal (heavy weight).
It has a handle on one side that you turn one way for crushed (fine) ice or turn the other way for coarse ice.
I put some cubes in and tried it -- works great!!
A functional and very useful retro kitchen item.
