Lucky you to have such a piece of memorabilia not only of an art gone by but...your grandfathers to boot. That's wonderful. I would display it with pride in my kitchen for all to see. Would be nice for when kids ask what it is. How nice a story you can tell them. Happy New Year, Friend!
HAPPY NEW YEAR to you, as well! And no, not on "display," lol--it's a working part of my kitchen! It even has a "chili grind" size on one of the disks, so I use that from time to time.
Has the little cone to fit in casings, if I make boudin, which I don't. But I bought some plastic casings once and made chorizo. That was good.
The last time I used it was to make pimiento cheese at home; I wanted those "worms" of cheese like in the commercial kind and couldn't do it with a regular grater. It worked perfectly.
