I think the whole thing is a change in the way we live now, as we get older we are able to time and financially afford these sort of hobbies that previous generations were unable to. They had come through a couple of wars and a depression and they were more interested in survival. We now are having people retire with some super to play with and we now recognize that some of the old stuff once considered rubbish was in fact very well made with the manufacturing ability of the times. This is a generational thing which may last another 20 years and by then all the old stuff in sheds will have been discovered and anything being produced at the present will have no collectible value. Can't see the Chinese stuff ever being worth much
