Years may pass and some one finds the drill and says who left this here?

Finders Keepers?

From what I remember about these machines they can back up a short distance, but are not made to back up the distance that they bore the total tunnel. They go to the end that they want to bore and then they many times back them up a little and bore a side tunnel and leave it there to rust away.
