Interesting Osram - GEC 50v 30w pip - top lamp

Click to view full size image

By far one of my favourite lamps found in the recent lot. A strange shaped lamp with a strange shaped filament, I haven't ever seen one like that before. Unfortunately the etch is quite faint but I tried my best to capture it in the second photo. This lamp looks very old indeed and could be from the 10s or 20s? It also has a strange voltage and wattage.

I think this was made between 1913-19 due to coiled tungsten filament, but still have pip here

Pretty, please no more Chinese failure.

It'll be all right in the end, and if it isn't all right, it isn't the end Smiley

There's a 28 inside a circle? Not sure if that's the date or not, as is imagine it is older than 1928.

The date code isn't usually the year itself, it can be wildly different depending on manufacturer and time period. Lamp dating is something of a black art, there are some that nobody has ever been able to decipher, but I've tried to learn as much as I can over the years.

A good place to start is James Hooker's Lamptech site. Also there is a web-based calculator that can give you some idea, see here.
