Vintage Harrison Home Products Arithma Addiator Manual Calculating Machine w/Instructions
Based on my internet research this device appears to be circa 1930's and made in Germany, but can't be sure. This mechanical calculator was apparently made in Germany and is in great working condition, with the original case and instructions inside and the little stylus as well. Use the stylus that clips nicely into the side to slide numbers up or down to add or subtract numbers. This amazing piece is so interesting and works great, and seems to be a magic trick when used. Great gift for those who love vintage machines and mathematics or for you to add to your collection.
Approx. Dimensions: 6-1/4" T x 1-1/2" W (without stylus) x 1/8" Thick
