The 1911 Sanborn map reveals a general office that is now two stories tall.  The office has been remodeled, and an ironclad firewall separates the area from the rest of the factory.  The office is labeled “not sprinklered.”  On some Sanborn maps NS appears in a black diamond-shaped icon to identify areas with no sprinklers.
The fire alarm box is now shown as FA in a pink circle.
