### Summary

The Chevalier Field Glass is a French optical device produced between 1860 and 1864. It features 3x to 4x magnification with an objective diameter of approximately 35 to 40 mm. The brass body is covered in Morocco leather and finished in blackened brass with polished fittings, weighing between 300 and 500 grams.

### Description

The Chevalier Field Glass was designed for field use during the early 1860s, offering portable magnification for observation in outdoor settings. Its 3x to 4x magnification range paired with an objective diameter of approximately 35 to 40 mm provided a balance between optical performance and compact form. The central rotating bridge or sliding focus mechanism allowed for adjustment to suit varying distances and conditions.

The construction centers on a brass body treated with a blackened finish and accented by polished fittings. Morocco leather covering protects the metal components while providing a secure grip. The combination of materials reflects manufacturing practices common to French optical instruments of the 1860-1864 period, prioritizing durability alongside functional design.

Weighing between 300 and 500 grams, the field glass remained light enough for extended carrying yet substantial enough to resist handling vibration. The finder specification of 100% at 0.8x magnification indicates the viewing field relationship. Focus adjustment through either a central rotating bridge or sliding mechanism gave the curator or field observer control over image clarity at different ranges.

Produced in France during the American Civil War era, the Chevalier Field Glass represents mid-19th century optical technology. The blackened brass finish reduced glare and visual detection, while the Morocco leather covering offered weather resistance. These design choices addressed practical concerns for observers working in varied environmental conditions during the 1860s.
