I bought a piece from auction at Freeman's in the USA. It arrived here in a 60kg wooden crate - inside which was a 5 kg carton held firm by short horizontal wood batons.
I could have spent the morning or longer trying to unscrew them but a chain saw freed the box in minutes. The box when opened is almost full of polystyrene crumb pieces. My static hands come out as though I had fallen in deep snow!
