The front of the base has +LL1, -LL1, A, D, DI, and K scales, with B, T, ST, S, and C scales on the front of the slide. The left end of the slide is marked: MODEL (/) N-500-ES (/) HI LOG/LOG.

- There is a black leather case lined with black plastic and marked below the slot for the flap with the Pickett logo in gold. The case has no belt loop. The case fits into a white, green, and black cardboard box. Compare to the box collected with 1995.0126.02. The bottom of this box has a flap marked: PickETT (/) WORLD'S MOST ACCURATE (/) SLIDE RULES. A blue and white sticker on the flap describes the slide rule's features: N500 (/) HI-LOG SPEED RULE (/) THE SUPERIOR TRIG/LOG LOG RULE FOR ESSEN- (/) TIAL ENGINEERING AND TECHNICAL NEEDS (/) All Metal construction for highest accuracy and lifetime (/) performance (/) 22 Key Scales with a comprehensive 60-inch log range (/) With Carrying Case and complete instruction manual (/) Lifetime Guarantee.
- 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.
