Meat my grinder

the audience that would be interested in this audience would be adults ages 28-45. 28 is just old enough to have established a separate life for ones self and start collecting all the things that it takes to furnish a house, (like antique meat grinders) and 45 is right on the edge that people older than that wouldn't be antique collectors, but would just have old things.
introduction to this object could happen in any number of ways, it may just be something that had formal qualities the collector found intriguing, or maybe they were decorating around an industrial kitchen motif. many collectors may have an affinity toward an object such as this because it was something that their grandmothers had in the kitchen and the nostalgia of the object attracts them too it. they always wanted to use it but grandma wouldn't let them for fear they'd break it or hurt themselves, so now they have their own to show grandma.
hobbies or carriers related to the object would be few that i could think of. i guess if someone was into sausage making as a hobby, (and yes this is a hobby) would be applicable. also antique collecting is a hobby and some collectors don't discriminate they just collect so they would fall into the category. as for careers that would use the meat grinder either chef, butcher, deli person.
feelings of nostalgia for grandmas kitchen, it calls to mind memories of the white hatted deli worker and the classic diner that serves "egg creams" and nickle sandwiches.
some one interested in an exhibit about this would be someone interested in the feeling of this time period when things seem so much more innocent and happy days. i think that possibly another person that my be interested in such a device would be a historian curious about uses of the archimedean auger, which is the interior screw portion that the meat grinder would not operate without.
