| (2) imprisoned between the door and the hinge pillar, and is instructed for SpectreCodename for Phantom III 3. (4) Front Ventilating Windows. On SpectreCodename for Phantom III 5 we have arranged that the front windows can be slid back to expose an opening 1" wide for ventilating purposes when required. There is nothing to whistle in this case when the window is closed and it remains to be seen what noise is obtained with the window open to different degrees of adjustment. Our experience with the Graham Paige, which is fitted with this scheme would suggest that there should not be much noise with the window slid back to the full extent.
