### History / Description

A fascinating vintage Japanese surveying compass manufactured by **USHIKATA (Ushikata Shokai)**, a Japanese surveying instrument brand.

This **Article No. 28 surveying pocket compass** features a distinctive green-painted metal body, a circular compass dial, finely detailed brass-coloured fittings, and an integrated sighting assembly.

The instrument bears the **USHIKATA – TOKYO JAPAN** marking, while the label inside its carrying case identifies it as an "USHIKATA SURVEYING COMPASS", Article No. 28, with a stadia ratio of 100 and a constant of 15 cm.

Its intricate mechanical construction and traditional surveying design reflect the character of Japanese precision instruments of the 20th century.

The instrument is accompanied by its fitted carrying case, featuring a blue fabric-lined interior, together with a metal plumb bob and cord.

### Collector Appeal

A visually striking example of vintage Japanese surveying equipment, combining technical craftsmanship with an elegant industrial aesthetic.

The deep green finish, contrasting brass-coloured components, graduated scales and carefully arranged mechanical elements give this instrument a distinctive appearance from every angle.

Particularly appealing to collectors of historical scientific instruments, surveying equipment, Japanese industrial design and vintage engineering objects.

With its fitted case and accompanying plumb bob, it also makes an attractive display piece for a study, library, office or technical collection.

### Condition

Vintage condition with visible signs of age, use and storage.

The metal surfaces show scratches, paint wear, tarnishing and areas of oxidation. The carrying case exhibits surface wear, scuffs and deterioration around the edges, with additional wear to its interior lining.

**During our inspection, the compass needle did not respond or move normally.** The compass mechanism may require servicing or repair.

The surveying accuracy and operation of the other mechanical and optical components have not been verified.

The instrument is offered primarily as a vintage collectible and decorative scientific instrument rather than as fully functional surveying equipment.
