Photos show everything. Not sure the ages, definitely very old. Each one is probably a different age, each one is a different maker, each a different condition. You can see in the close-ups the names and numbers on each one. They show rust / patina, as you can see. The JEWEL has a GRISWOLD handle/crank on it (photos four and five). I believe it is the original, but I can't find much information on JEWEL / GRISWOLD meat grinders. It certainly appears to be the original crank, however. The last two photos show the KEEN KUTTER and the plates that were on it. I do not know if they are original plates to the grinder, but this is how they were. Please look closely at it, the last two photos. Please use the zoom feature and ask any questions you may have.
