六分儀 - 烏木 - Hughes London - 独特的乌木六分仪

一件由 Hughes London 制作的独特乌木六分仪。该仪器很可能在 1838 年至 1875 年之间制造，是19世纪海事工艺的辉煌典范。尽管木制仪器配有白色刻度盘，在技术上通常被称为“八分仪”（因为测量弧度为 45 度，适用于测量至 90 度），但同类型号在民间和水手之间也常被称作（乌木）六分仪，而本样品的测量弧为两段各 60 度的组合，便是一个例子。
• 雕刻“Hughes London”：白色板上的铭文有助于确定年代。著名的 Henry Hughes 于 1838 年在伦敦创立了他的公司。
• 材料与结构：在十八世纪中叶至十九世纪中叶，黑色乌木框架配以对比明显的白色刻度弧（底部的白色刻度）及铜制部件，成为当时经济实用、可靠导航仪器的标准。到 1870/1880 年代，企业几乎全面转向使用金属（黄铜或青铜）的“三圆弧”六分仪。
关于制作者：Hughes London
Hughes 家族是英国最受尊敬、影响力最大的仪器制造世家之一。
• 起源：家族最初在 18 世纪就已作为钟表匠在伦敦东区活动，后将专长扩展至航海钟（航海上历表）和为改航经由泰晤士河的船只设计的导航仪器。
• Henry Hughes & Son：1838 年，Henry Hughes 在伦敦海事核心区的芬奇乔街 59 号开设了知名的商店与工作室。该公司向英国皇家海军以及商业贸易船队提供高质量的光学与导航仪器。
• 后来史：1903 年，企业更名为 Henry Hughes & Son Ltd。二战伦敦大轰炸（1941）摧毁了他们的办公室，随后与另一巨头 Kelvin Bottomley & Baird 合并，形成了如今知名的 Kelvin Hughes 品牌，至今仍作为现代海事雷达系统与导航技术的制造商存在。
遗憾地是，这件物品仍能看到若干缺陷。乌木框架缺失了一部分，以及若干镜片缺失。对于合格的修复师而言，这并非难题，完全可以将六分仪恢复至良好状态。」}json userassistant पत्थर देवनागरी not allowed:analysis to=final code apologizes to=final 0 js?Oops? I already provided.
