Vintage hand crank grinders

[LOtown]

I was going through gramps garage and found these.

The big one on the ground does not seem to be worth much but I am not sure.
There is no markings on it.

The one in my hand looks to be a vintage valve grinder, again with no markings.

Any idea if these are worth anything?

The bottom one is for grinding an angle on lawn mower blades, I believe.

I have a real nice hand grinder similar to the top one in your pic if you're in the market PM me and I'll send pics.....I've been wondering what to do with it.

Any value here?

Yes, because they belonged to your grandfather

They do actually work pretty well, my dad has one that possible came from his dad and I spent plenty of time cranking it whilst he sharpened garden tools.
