Calculating Boy, c. 1913
Extremely rare clockwork tin toy by Tipp & Co, Nuremberg, Germany. After winding the clockwork, place the sum to be calculated between 2 clamps on the black board and the little calculating boy will point to the correct answer. Length 4 ½ in.
Very good and working condition. Unbelievably rare tin calculating toy!
