Chandeliers were designed to be rewired at the point of sale or installation. Large Chandeliers especially would be fitted together at the location and the cabling installed as the fitters worked.
Consequently rewiring is generally a simple process to do and for old lights well worth doing even if the cabling is intact.

Your local electricians will be able to rewire and add new bulb mounts if required.
However if you would like to do it yourself this page gives an idea of some of the parts easily accessible online.
