Lancaster Antiques has dated this piece to the 1920s.

The lights are approximately 14.5cm in width; and the length of the longest drops up to the central hook is 30cm; the longest glass lustres being 21cm in length.
Our electrician recently rewired both lights to UK specifications, and attached an additional 33cm of chain to the frame so that they can hang from the ceiling hooks. We can supply chrome ceiling hooks if required at no extra cost.

It is difficult to date the lights as the drops are late Victorian - early 20thC, but the chrome ring could be from around 1920's, so they were possibly made to order around that time.
Postage and packing within the UK mainland only is included in the price, and we will be happy to supply quotes for delivery elsewhere.
