There have been a lot of changes at MOTAT since you took those photographs in 2007. ZK-AMO was removed from the display hall and stored outside while a HUGE new display hall was constructed, with the new display hall opening late last year. A few months ago, the Solent was shifted into the new display hall and a major restoration has started (as you can see in the photographs taken in the lower deck last Thursday). The previous restoration was mainly cosmetic inside, but they are now dealing with a lot of accumulated water damage from the decades when it sat outside, as well as corrosion in a number of places. Work is also progressing on the Short Sunderland, which is still outside, however they are planning to move the Sunderland into the new display hall at some point in the near future. In fact, they are planning to move their entire collection that is still outside into there within a reasonable period of time. Currently, only the Sunderland, the Lodestar and the Ventura are parked outside, but not for too much longer.
