Winterfell - S8-E1
Visible crew/equipment: After Sansa tells young Ned Umber to hurry back to Last Hearth and bring his people to Winterfell, when Jon tells Maester Wolkan to send ravens to the Night's Watch, in the next shot of Wolkan the chalk T-mark can be seen on the stone floor in front of his feet (it's not the stone's edges or cracks).
