| 1021 Rm{William Robotham - Chief Engineer}/EAC.1/ET. 20th March, 1941. The Perfecta Motor Equipment Ltd., Excelsior Works - Oxford Street, BIRMINGHAM. 5. Dear Sirs, As arranged with your Mr. Bach a few days ago, we are sending you herewith blue prints showing a modified spindle and handle of the windscreen regulator that you are making for us. As explained to you, we should like one of these to have a black celluloid covering, as marked on our blue print. No allowance has been made for the thickness of celluloid. Regarding the finish of the second one of the two which you have on order, we will let you know later what finish is required. We are trying to find a finish that will be less glaring than chrome, and we shall probably decide on an oxydised finish, but will let you know as soon as this has been settled. Yours faithfully, Blue prints attached:- MB.116 - Assy. Windshield Regulator. MB.126 - Windshield Regulator. MB.127 - Knob. Windshield Regulator. MB.129 - Screw. " " MB.133 - Escutcheon " " | ||
