What Is It?

Okay, all you vintage sellers, buyers, collectors, experts...  What is this?

I'm assuming it is some sort of food masher, but does anyone know exactly what it was used for?  It belonged to my Grandmother, and I recently pulled it out of a cupboard to display for awhile.  Of course, neither grandmother is around today to ask.

Thanks for your input!

Have a good start to the week!
