Estimated Early 20th-century wooden abacus with a dark hardwood frame and turned wooden beads strung on metal rods. This four-row abacus features many beads, each moving smoothly across original steel rods.Constructed with visible round head nails and mortise-style joinery, it exhibits a hand-crafted, utilitarian aesthetic typical of schoolhouse teaching tools from the period.
The frame shows authentic age-related wear, including surface abrasions, minor cracks, and patina to both wood and metal. Beads remain intact and functional.A visually engaging artifact ideal for display in a study, office, or folk art collection. Vintage condition consistent with age as pictured.
