very old French Chandelier

My wife fell in love with and bought in a "Depot Vente" an old French chandelier.

Needless to say it was incomplete. I require 7 bushes to mount onto the spigots to connect to UK standard SBC fittings, I have spent some time in a very knowledgeable tool shop who inform me that the thread in the spigots is rolled. ( I wish I knew what that meant) and the nearest screw thread was BSP. I am willing to bring the chandelier for examination and measurement, upto 100 miles from Watford. Can any one help me for the sake of matrimonial hormony.

If no one else volunteers and You want to post "across the pond" I would help.

Hi Ian, The thread being rolled means it is formed by forcing a revolving die onto the material, instead of cutting with a die or on a lathe.This produces a more round top to the thread and they are generally very even to, bit sometimes a cut thread nut does not easily fit a rolled thread bolt. The thread will be either a small version of BSC (british standard conduit) or possibly brass thread, you will have to see what thread is in the lampholders before you commit, they could all now be metric! Is it something like this http://www.amazon.co.uk/Elektek-Nipple-Fitting-Threaded-Holders/dp/B007MPBSEI/ref=pd_bxgy_60_img_y

or is there a thread in the chandelier, in which case you need a 3/8" or 1/2" brass nipple. All metal light fitting, don't forget to earth it!
