The package for the lamp writes:

Metal (Tungsten) Lamp
Made with Drawn Wire Filament.

Therefore this lamp was probably made somewhere between 1911 and 1920..??

That date could well be right, the package does look very old as well 1911-1920 many thanks, don't know where I got that lamp from?

Interested in the history of electric lighting and incandescent in particular and neon glow lamps.

I would say it is a later model Seems to be tipless which it may be made after 1919.

Pretty, please no more Chinese failure.

You have a valid point there Robert, no pun intended. Perhaps the lamp does not belong with the packaging.

I'm not one for arguing, but wasn't the "drawn" tungsten filament exploited for about a decade staring in 1911? Then coiled tungsten filaments and gas-filled bulbs quickly took over?

A better image focused on the filament is the pic at left.

Hi this lamp has caused much interest, cannot remember where I got the lamp from boot sale? maybe can only think the package was the correct one the names are the same but this means nothing, Would James have any idea??
