Collectible Focus: The Vintage Bulb (ca. 1910–1920)
An exceptionally valuable overall piece is the large, intact and fully functional incandescent filament bulb:
Shape and Blowing Technique: Globe-shaped form (pear/squat shape) characterized by the classic "pip" (the glass closing point at the top), evidence of artisanal mouth-blown and manually evacuated air production.
Squirrel-Cage Filament: Inside there is a continuous filament suspended on a refined central spoke-like support, designed in the early 20th century to ensure maximum light diffusion.
Era: The combination of the glass tip and the filament architecture places the bulb’s production between 1910 and the early 1920s of the 20th century.
Luminosity: When lit, it emits a suggestive warm light at a low color temperature that highlights the filament interweaving.

Conditions:
The lamp is in good conservational condition with a splendid natural patina on the brass and light signs of aging in keeping with its age. The electrical system is functional and the bulb is intact and lights up regularly. Prospective buyers are invited to view the photo set carefully, which constitutes an integral part of the description.
