i have looked through the aums for an example of what i am after but can`t find anything. i want to change between two models in game, one is the ship itself

the other is the bridge of the ship

i have a camera code set for 3 views one of which is an fps view (which will be the bridge view) could anyone point me in the right direction for something like this?
the camera to go into fps is actived by 2 btw. i hope i`ve explained this ok
