I've had my fifteen minutes of fame, now for the rest of the story. I probably spent three hours pouring over the internet looking at antique farmers tools looking for this tool to no avail. I knew that I had seen this tool, probably when I was at my grandfathers farm years ago but for the life of me couldn't remember what it was. Denny Ford came to the rescue after I posted pictures on Facebook. Bob Walker chimed in with the answer shortly after. So no, I only know cars, booze and guns and not very well.
It came from Ann’s Grandfather’s collection up in Delaware. Ann said he grew corn! Her family were railroader’s also so I had no idea. But it seemed as all the railroad collection was engraved with PRR. Thanks to everyone that helped. Bob W and Denny
