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.
In a long pole shed toward the rear of the machinery area are a bunch of tractors, mostly tracked. This little
Cat FIFTEEN is in the group. An unknown number of these were made by Caterpillar from 1928 to 1933, at a base cost of $1,100 in 1932. A little bigger than the TEN, they weighed 5,500 lbs. and had a 3.6 litre gasoline engine which produced 25 belt HP. Strangely, its tested drawbar pull, at 4,166 lbs, was less than that of the TEN, which weighed 1,000 lbs. less. Like the TEN it had a three speed transmission.
