Concrete wall on top of 7405 was likely constructed as part of a reorganization/renovation of room H-10 and the trapezoidal structure. 7406 maintains the line of 7405 and likely extended further west and east but is not preserved. At a later point the western portion of 7406 was truncated by cut 7266.
