Lamps converted to electric.
A number of lamps come up on the auction sites that
Have been converted to electric bulb, what is involved
In converting these lamps back to wick and oil, is it worth
Doing or to expensive.

If its a common lamp and has been converted to 240v big diameter fitting, just buy and use it for spares if fit for that purpose - not worth convrting back, you can buy complete ones cheaper. If small fittings and the original bits are mostly there, it could be worth converting back for own use. There would be no profit in it to sell it on.
However if it is a rarer lamp, it is a different picture! They are more often than not well worth converting back.
I bought an Edwards Stevenson which had been electrified, a couple of years ago. Imagine my joyfull suprise when I got it and inspected it. I took the wood plinth off and found a small gauge wire had been drilled up through the vessel, but the burner and pr-cker were still there, the wire had been fed up the round wick tube and a pigmy brass bulb holder soldered to the top of the wick tube. The gauze was intact, even the inner glass and copper smoke cap were all there. It took hardly any work and little cost to make as new and the lamp basically was as new (Job was that important, I asked Maurice Dawson to do it for me! - and what an excellent job he did) It's one of my favourite lamps - a Stevenson and to cap it all - made just a few miles down the road from me in Wakefield - a local lamp!!!
If in doubt ask on the forum.
