label: Description
content: The guarantee, with a registration card, is in the bottom of the box, along with the plastic bag that originally contained the slide rule inside the case. The registration card indicates that this example's serial number is A103202 and that the company's headquarters were in Santa Barbara, Calif. The company moved to Santa Barbara in 1964. Along with the logo, this suggests the slide rule was made in the mid-to-late 1960s. Students typically purchased this model in college and continued to use it in their careers.
