John i think they were only joking..
I think the point that Sandor is trying to put across is that the Chinese manufactures very rarely ( If ever ) go in depth enough to use the correct Ral numbers for their models.
Until last week I owned the exact same model as in your photo link and when I tried to match the paint I found it was quite some way off from the full size. In the end I mixed my own using acrylic based paints then had a paint shop match it and put it in a can for me. I have a bottle of the blue left if you want it..
