Fort Missoula, for nearly a century a military fort, is now a National Historic Place and park. In the park are a few of the pre 20th century buildings from the original 1877 fort and many buildings from the early 1900s. They have an eclectic collection of large artefacts, including machinery and tractors, a lookout tower, railroad engine and cars, a tipi burner, the old Drummond, MT RR station, an old school and an old mission, artillery and a historical museum. It's a great place to spend an afternoon or a whole day.
One of the outside displays, one will find this grader hitched to the Cat D6 in the centre of the display area.
This pull grader #77 was manufactured in 1928. It has been restored and repainted. You'll notice that it's painted gray. Here's a hint on dating Caterpillars. On December 7, 1931 Caterpillar changed its corporate colour from the familiar gray to the present day yellow.
