| Re Ventilators in Dashboard. Mr Spinney 21-11-12 TBB18/L211112 Will you please instruct one of the Experimental cars to be fitted with a second set of circular ventilators in a higher position, so that the hot air emerging from the louvred bonnet will not enter the front floor space. The first set of circular ventilators should remain in position on the experimental car. | ||
