Colours are different to ours think white and black and I don't think I would want to try and rewire any lamp for what they cost hardly worth it. It would most likely work OK but I know I have had to condemn many US 110 volt items as not suitable for our system.
Definitely don't feel competent with electrics. My electrician does not want to do it. Is it really such a big deal? Should I just keep asking different electricians until someone says ok, or rather go for an antique restorer (which will inevitably be pricey).
Don't go to an antiques restorer he will not be able to do this legally for the same reason you cannot legally sell second hand electrical equipment at a boot-fair.
If the wiring is in reasonably condition ie not coroded, & just has blk/wht. colours then why not over sleeve them brn/blu. and if fitting is metal then ensure an earth wire is connected effectively to the metalwork and of course to the circuits earth.
As you will be running the light[s] at half original current wires will be large enough and a simple IR test will confirm quality of insulation, am I missing something here as I can't see a problem??
