We are forwarding to you - 2 Clutch Plates for our 40/50 HP. car. A few days ago Mr. Field visited us and showed us a number of clutch plates upon which the friction fabric was moulded. We should be obliged if these clutch plates could be treated in this manner, and if possible, the same material used as is at present employed on our friction clutch discs. One important point in connection with these discs is that their finished thickness should not exceed .312". As we are anxious to get some tests through on this type of clutch plate, we should be obliged if you could expedite the delivery of these clutch plates, and also those for the 20 HP. which we have previously handed to you. Yours faithfully, | ||
