Carbon Filament Light Bulb

Here's a genuine antique carbon filament light bulb. It's 375 watts and was originally meant for 110 volts (currently in the USA we use 120 volts AC). In the photo, the bulb is running from 50 volts.


Perhaps someone out there has more information on the age of this bulb. I think it's around 60-70 years old. It's not older since it doesn't have the glass seal on the top of the bulb.
