What surprised me the most was that I saw objects that must have there since I was a child, but had either never seen before or had completely forgotten about. Perhaps the best example of this was the James Watt cast and mould of an urn.
It's going to be quite a problem getting data because the popularity of the objects seems to range from no interest at all to completely surrounded. I guess that's why the ship models are no longer on display. Farewell, Deep Sea Diver! Goodbye, Clocks! Nice to have known you, Combine Harvester!
