賣家描述
Koizumi Sokki Seisakusho KP-26 – Correction Planimeter
– Needle-type planimeter
– Zero-return device
– Model KP-26
– Compact vintage measuring instrument
Dimensions of case: approx. 28 × 9 × 4 cm
Summary: The Koizumi Sokki Seisakusho KP-26 is a vintage needle-type correction planimeter with a zero-return device. Its specialised form reflects the practical precision instruments used for analogue measurement and technical drawing.
The instrument combines a measured, purposeful layout with the distinctive arm and pointer arrangement of a planimeter. Its compact construction gives it a clear place within a collection of Japanese scientific instruments, surveying tools or historical design objects.
The KP-26 model designation provides a precise identity for collectors researching Koizumi measuring equipment. The zero-return feature adds functional interest and helps explain the instrument’s intended technical use without changing its restrained industrial character.
The body is described as comparatively clean, while long-term storage has caused marked deterioration around the outer surfaces. Operation has not been tested because the method of use is not confirmed. The object is therefore best approached as a vintage measuring instrument requiring careful inspection before practical use.
