Vicky Thomas Antiques has dated this piece to the Victorian era.
Its really unusual to be extendable as a table lamp ( rather than a floor or standard lamp ), and this makes it very versatile.

I have had the lamp professionally rewired by an Antique lighting specialist and offer it for sale with the lamp shade ( although I understand that a green and white striped shade might not be to everyone's taste!). This is just a modern shade that I bought to take the photographs, so it comes free of charge if you want it!

I have left the lamp unpolished so that you may decide how you would like it to be presented - but as it's solid brass, it would polish up a treat if that's the look you're after.
Please do not hesitate to let me know if I can provide any further information or photographs.
I offer free postage across the UK, and am very happy to help with quotes for shipping abroad.
