Instructions
Visit the official Hess website.
Click "HESS Truck History."
The entire Hess Truck product line, beginning with the first Hess Truck in 1964, is broken down by decade.
Use any clues you have about the truck's general age to browse to a reasonable time frame. When did you receive the truck? How old does it look to you? Use answers to questions like these to avoid having to scroll through every single vehicle produced by Hess.
Some trucks have only subtle differences from ones produced in previous or later years. Don't assume that your truck was necessarily made in a certain year, simply because it looks similar to a particular model. Read each description carefully. Hess' descriptions of each truck are very detailed, and will help you pinpoint exactly when your truck was made.
