The deflector dish opening to reveal a gigantic shuttle? common...WTF?
I have an old Corgi TOS Enterprise model that opens up the secondary hull like bomb-bay doors to release its bright orange shuttle. And it fires photon discs out of the saucer.
The Mego TOS bridge playset has a transporter where the turbolift doors should be.
The TMP bridge playset has a round airlock door in the wall.
The Playmates TNG Engineering playset connects to the TNG bridge.
