My grandfather had one of these. It was passed down by my great-great-grandfather, who had it delivered to him after he and his family pioneered to northern Michigan shortly after the Civil War. He used it on the farm and we have some old pictures of him holding it in front of the cabin (which still stands, by the way). I remember it still worked when I was little. Unfortunately, I have no idea what happened to it. It wasn’t among my grandfather’s possessions when he died at age 100 a couple of years ago.

If it was worth $100,000, then it's dadgum worth looking into.
 
As people become old & infirm & decrepit [Alzheimer's, Parkinson's, etc], the nice things in their homes have a very bad tendency to sprout legs and walk away.
 
If there isn't firm documentation that your Grandfather sold it, then you likely have an aunt or an uncle or a cousin who is sitting on a very nice piece of hardware.
 
Or else someone from the Home Health Agency snagged it.
 
Seriously.
 
Stuff like that needs to be accounted for.
