Sorry Chris, but you are mis-informed regarding the Shuttle Tydirium.
The Tydirium is a Lambda class shuttle that is a common cargo and troop transport ship used mostly by the Empire. The Tydirium was stolen and used by the commando force to insert onto the planet Endor.
There is no reference to either the Emperor or Vader using this shuttle, as they had there own personal versions modified for them. The Emperors shuttle had upgraded weapons, upgraded shields, personal quarters and a cloaking devise was rumoured. Vaders had a meditation chamber so he could remove his helmet/armour.
The shuttle above looks great, and the weathering is realistic.
