We established here:
Who signed the Captain Picard Day sign?
That the Picard Day sign from Star Trek: Picard is not the same as in TNG.
However we've also seen
Worf's batleth, a model of the Stargazer, and a disassembled B4, with presumably other Easter eggs to come
Which props in Star Trek: Picard are reused from the original TNG show and films (if any)?
To be clear, I'm asking about props meant to represent a specific object recurring, not, for example, a random phaser or communicator.
