EXPAND YOUR POST COLLECTION: Add a vintage Frederick Post No. 1447 slide rule manufactured by Hemmi in Japan. Its 10-inch scale and matching Post-branded hard case make an appealing pairing for your mathematical-instrument collection.

EXPLORE CALCULATION BEFORE ELECTRONICS: Labeled A, B, CI, C, D, and K scales provide a hands-on introduction to slide-rule relationships. The clear cursor lets you follow corresponding positions across the scales, bringing mechanical calculation into your educational display.

READABLE SCALES WITH BRANDED STORAGE: Scale markings remain readable, and the cursor and two-piece gray case are included. The instrument has light surface wear and age discoloration, with wear to the cursor frame and case. No instruction booklet is included.
