Slide rules HOME page COLLECTION 5" RULES
Make Sun Hemmi, Japan
Model No. 074

1. Rear of slide has two fixed clear plastic "cursors" to allow use of trigonometrical functions without need to remove slider.
2. Marked "Made in occupied Japan". Rules with this marking are relatively common. (Had I realised this when I bought it I might have thought twice about buying it - but, on the other hand, it still brings back memories of the San Telmo market in Buenos Aires.)
