Antique micrometer caliper 

Antique micrometer with its original wooden box; French manufacture, signed, from an old screw factory. Beautiful to display in a display case or on the desk of a sector study; for those who do not know it, this instrument is used to measure very small lengths with great precision. We are always happy to be able to recover old instruments and old tools used by both the professions of the past and those of today - in a clearly updated version.
