AI-assisted summary
Description from the seller
A unique and museum-worthy opportunity for collectors of scientific antiques, industrial history, or maritime heritage! I am offering here a beautiful, complete set consisting of a heavy brass Control Manometer (gauge) and the accompanying, custom-made wooden transport box.
The instrument and the box belong inseparably together. Inside the lid, the original metal factory label from the renowned German quality maker shines:
"C. WILH. STEIN SOHN – MANOMETER-FABRIK – HAMBURG"
This type of precision instrument was used around 1900 to check and calibrate the accuracy of other manometers for steam boilers, in laboratories, or in the engine rooms of large ships.
Unique features of this complete set:
Perfect fit: As shown in the photos, the heavy brass instrument fits exactly into the left section of the opened box. The interior is ingeniously designed with wooden guides to fix the gauge vibrationally.
Green felt lining: The inside contains the original, characteristic green felt cushions that protect the delicate glass and brass from scratches and bumps during transport.
The Manometer: Fully made of solid brass with a crystal-clear double-arc scale (0-30 Atmospheres) and a mirrored background to prevent parallax errors when reading. The central logo with the German Reich Eagle is beautifully preserved.
The Wooden Box: Made of sturdy, solid wood with authentic dovetail joints at the corners, sturdy metal hinges, and two metal hasp latches at the front.
