TO-1 (F-80C) Fighter TO-2 (T-33) Trainers Flight Computer Set 1948-49
Here is an interesting pair of Flight Computers, both for the US Navy's versions of the Lockheed Shooting Star Jet Fighter Trainer TO-1 (USAF F-80C) and the two-seat Trainer TO-2 (USAF T-33) dated 1948-49.
The first is the Rest Computer. The Rest Computer was designed for simple solution of level flight cruise control problems. It is a 3-disc circular slide rule.
The second is the combination Climb and Descent Tabulator and Maximum Range Tabulator. It is a 2-disc circular calculator.
Both measure 7 inches diameter and are in very good condition given their age. A unique find indeed.
