RARE 1950s-70s Abacus Calculator American School Classroom Teacher Demo Size; Made by USA Manufacturer NUMBERAID

Historical piece of American classroom learning and teaching.

The abacus is not for sale at the moment but we are interested in meeting teachers or persons who may have used something similar when they were growing up in American Elementary school classrooms in the 60s or 70s. This is the teacher version.

The student versions were much smaller and made of plastic.

Perhaps you grew up with a slide rule or other hands on manipulatives that made it easier to understand math. Or maybe you have a teacher size abacus like this one.

Large metal frame with wood discs. Most abacus have round balls but this one has flat wood discs with notches in primary colors of blue, yellow, white, red and green. Has vintage patina and the word "Numberaid" can barely be made out. Measures about 12" x 12" x 1"
