VISIT TO SALES ON 10TH. INST. X.4613 - 20 HP. SCUTTLE ISOLATION. X.4613. It would appear that now we virtually isolate the scuttle from the dashboard, it is wrong to attach the instrument board to the dashboard and to the scuttle. We therefore feel inclined to suggest that on 'B' type cars the instrument board brackets should not be used, but the instrument board should be attached to the scuttle. On 'D' type cars where we need the off side instrument board bracket as a support for the steering column, this bracket only should be fitted, and the instrument board should not be attached to it, but supported entirely from the scuttle. We can demonstrate that when the instrument board is attached to these brackets and to the scuttle when driving over rough roads they force the dashboard to hammer against the end of the bonnet and cause rattles. We have tried the above suggestion on several cars and met with success. We would like Mr. Royce's views, and suggest that a self supporting 'D' type column would be an advantage when we could provide the same.
