Friends,

Hi Stan,

I have seen a lamp similar to this, but made under the name Brittania.

It is in an 80mm diameter globe, and has four 25W ring-shape coiled filaments.  The four filaments are stacked above each other vertically.  It has a bayonet cap with a push-button switch on the end of a long hanging cable, and each time you push the switch it lights up an extra filament to give you 25/50/75/100W.

I believe this lamp was made by Metropolitan-Vickers (Metrovick) factory in Brimsdown, London around 1925.  Is yours similar?  I will try to do a photo.  Probably quite a few companies made this kind of thing in the early days.

Best regards,

James.

Hi Guys!
Such a lamp sounds like a fantasy film gadget!
I would like to see a picture of that interesting bulb.
