Early Edison-style lamp with loop carbon filament and hand-sealed exhaust tip. Brass screw base stamped “Germany.”

Based on construction and filament style, this bulb likely dates to circa 1895–1905 during the early era of electric lighting.

Features:

• Loop carbon filament

• Hand-sealed glass tip

• Brass Edison screw base marked Germany

• Early export bulb

The filament appears intact. The bulb briefly illuminated when tested several days ago, but due to age it is being sold strictly as a collectible display item and not guaranteed to function.

No cracks observed in the glass.

A nice example of early electric lighting history.

Also the bag I found it in comes with the bulb.
