Virginia is a body 1 face 11 Realdoll, Lina is body 8 face 6, Caroline is body 6 face 5, and Rebecca is body 4 head 4. (Rebecca was made before the change to removable faces.)

Oh, yeah; Caroline is Rebecca's mother. (How much fun is that?!)

The title of this page, Requiem for a Wren, sounds a bit dire, but it is the title of a 1955 novel by Nevil Shute.
