For sale here is an early, antique, unmarked, Edison style, framed filament, thin glass with nipple top, lightbulb. Likely dates to around 1920. Just over 4 inches across. Bottom metal part missing. Obviously not working. Just for display only. Some wear and some stain as it was dug in an old bottle dump. Great to look at the inner mechanisms for studying historic electricity and lighting. Please review photos and feel free to ask any questions. We do combine shipping. Shipping to the US only. Thanks for looking.
