If what you want has disappeared then buy something that's reproduced using the same level of skill, design and material, and contains that ingredient called quality. Some salvage-oriented businesses are a victim of their own success. Demand is increased by raising public awareness, so replacing the stock becomes harder. They look at it from the angle, 'well, you can only sell an original once, so copying it is the way forward'. As it's an easy way to make money, outlets are springing up everywhere and many have no experience of old shapes.
China is mass producing all kinds of reproduction - good and bad.
I saw a Chinese copy of a Victorian fireplace - it was the first time I'd seen cherubs with Oriental eyes. I've heard of some cracking under heat. Under that newly painted surface could be filler, an obvious sign of poor quality. Now, top dealers are using their knowledge to remake old designs. Using proportion as a guideline, they're keeping the essence of the original concept alive.
