Factory Entertainment’s replica has been copied directly from surviving resources in the CBS archives to ensure accuracy.  It is milled from solid brass alloy and hand-painted to suggest a vintage finish, and is completed with a wound cord tassel decoration. The storage box is cast from polyresin and lined with EPS foam. The flute appeared in several episodes and, as is normal for productions, some small modifications where made to it over the course of time. This replica has been designed to capture them all in single blended execution. The Factory Entertainment development team understood that the melody we hear is intrinsically linked to the prop and as such we wanted to include it in some way, but this represented significant technical and licensing challenges. Our solution was a concealed audio feature in the storage box that, when activated, plays digital audio taken directly from the original soundtrack of the episode.
