BENTLEY V and BENTLEY V.{VIENNA} 'CORNICHE' (14-B-5.).

D.CD.1245 STEERING COLUMN - MOD. TO CONTROL QUADRANT AND ADDITION OF OIL SHIELD AND BUSH.

Owing to the addition of controls with the conse-quent reduction in space available for the horn cable, we are compelled to use the non-oil proof, small diameter type of cable again.

To protect this cable, the scheme shews a rubber shield fitted at the bottom of the steering column. This shield follows the design of the one previously instructed for the Wraith chassis to D.CD.627.

The scheme modifies F.CD.1200 and F.CD.1211 in that the control quadrant has been altered to accommodate the Phantom lll two tone switch, which we understand is preferred to the Wraith type.

As high frequency horns are provided on the Corniche, a two tone switch is not necessary. Therefore, we propose to use the Phantom lll switch, with a plain push button, the twin cable ends being attached to one terminal in the horn disconnecting box on the frame.

It is most important that the horn button assembly should include the rivets, added to prevent rattle. These are shown on D.CD.598.

Bentley 5. Instruct experimentally and for 50 sets, similar to F.CD.1211.

Bentley 5 'Corniche'. Instruct similar to F.CD.1200.
