Part 3 Colors and markings used on Forest Service vehicles 1965-2009
By Aaron Woods
In the mid 1960s there was another change in markings. The red, white & blue shield was replaced with a small (6”) brown & white USFS shield. A solid brown box with white trim replaced the earlier white outline. The use of radio ID numbers started to appear on fire vehicles in the early 1970s.

Part 2 Colors and markings 1905-1965
By Aaron Woods
Before getting into specifics it should be explained that from the very beginning the USFS has been run as a decentralized organization allowing the individual regions and forests much autonomy in their operations. As a result there are a lot of exceptions to the rule when it comes to the vehicles used by the agency.
In the early days of the agency, vehicles were often the personal property of the employee and were marked at the discretion of the local forest. Most simply had a removable sign on the front and / or sides to identify it as an official vehicle.

Before I get into the vehicles used by the USFS a little background of the agency is required.
The USFS was created in 1905 to manage the Forest Reserves designated during the 1890s. The USFS is the only Federal wildland fire agency under the Department of Agriculture, the other 4 large agencies (National Park Service, Bureau of Land Management, US Fish and Wildlife, and Bureau of Indian Affairs) being under the Department of the Interior.

At the close of World War 2 the US Army ordered a new and large crash truck to serve at stateside airfields. The Class 155 was the result and it was built on either Corbitt, Brockway or Kenworth chassis. It was a large truck, carried 1000 gallons of water, protein foam and had to large deck turrets for discharging the water foam mixture. The Hale pump was powered by a Continental engine. Here is a photo of the truck. I chose to model this truck because it was both a piece of fire apparatus and military oriented; something I don’t have in my collection.
