This is an antique Universal Meat Grinder. It comes with 3 blades. Mounts onto the side of a table or board. The whole unit disassembles. The number '41' is on the top of the grinder, and the name 'Universal' is on the handle. During my research I found no others like this one. The top has a square opening. The wooden handle is not 'curved' - remants of decorative stripes on the handle, see photos. This is a very heavy item.
