Meat Grinder Noob Question

Hello everyone. I have been gifted bunch of meat grinding hardware but Im kinda lost about it. instead of all having a circle with holes like I saw years ago, most have some sorts of lid on it. when I remove it there are something inside but not sure what it for. See pictures. Could somebody explain to me what it is or point me to good reference about it.

There was also bunch of cones in the box too. they seem to be meant to grate but with what ?

here is more

One of them looks like a grain mill.  20170306_185541_resized.jpg

I agree with Tyler. That one looks like a grain mill. The green thing looks to be an apple corer. The others look like meat grinders to me.

these pictures are better. I figured out the cones.

Oh, you have some exciting goodies.

I don't know if I see a meat grinder there, but you have a food chopper like this



you can see it's a food chopper because the 'blade' is on the outside.

I adore my food chopper more than any other gadget in my kitchen. It's the predecessor of the food processor.

I also see the tool that makes apple rings (it cores, peels and slices the apple all at once) - it's the green one.

Yeah its quite a treasure a got there. person was gonna throw em out

ok so it makes food chunk instead of grounding ??

also some of them start ot have rust on them how should I clean them

Mostly.  It's really awesome for leftovers.  Like transforming roast beat and leftover veg into shepherd's pie.  

But, some have special ends for making bread crumbs and even nut-butter.  The bread crumb one looks like a grain mill attachment and the nut-butter one is quite smooth with occasional gaps.  

Remind me, I'll take some pictures of mine tomorrow (I have a collection growing - I love them so much).  

After my knife and fry pan, these are the most used items in my kitchen.
