This universal double tube injector survived the Silver Valley Idaho Great Fire of 1910 which burned 3 million acres of forest land and destroyed numerous towns and structures.  It is believed that it was the largest forest fire in U.S. history.  This double tube injector was recovered in the fire's aftermath in Northern Idaho.  As it has survived this epic historical fire, the valve body has sustained a slight warp and it is missing some of its original parts.  It would make a great addition to a railroadania collection.
