For sale is a vintage Pickett Model N4-ES Vector-Type Log Log Dual-Base Speed slide rule with original leather case.

This is a very nice example. The scales are bright, clean, and easy to read. The cursor shows some light wear from age and handling. The original leather case is included. Under the flap, the former owner's name is written, and the back of the case shows a mark from a removed Dymo label.

Please review all photos carefully. You will receive the exact slide rule and case shown. Condition is as shown in the pictures. If it is not shown, it is not included.
