Old Japanese abacus, possibly dating to the 1970s or early 1980s – all pieces in place and fully functioning. This piece is particularly unusual as the push on one lever can reset all the pieces to their starting position. Ideal as a small decorative piece.
日式老算盤，年代推測約為 1970 年代至 1980 年代初期。所有算珠均完整無缺，功能正常，可正常使用。此件較為特殊，只需按壓上清零桿，即可將所有算珠一次歸位。尺寸小巧，適合作為裝飾擺件。
