| - 3 - Messrs. Park Ward & Co., Ltd. DIRECTION INDICATOR Yet another source of noise is the air passing the cap around the direction indicators and we would like these edges to be radiused off in a manner similar to those of the door shuts. We are continuing our investigations and before you get too far we may have some further recommendations to make to you. The writer will call on you in the course of a few days to see these modifications, after you have added them to the full-size drawing. Yours faithfully, For BENTLEY MOTORS (1931) LTD. | ||
