Coverley - Production Engineer}/MVF. re Phantom III Engine Suspension Bracket. We have completed and issued a revised design of front engine suspension bracket LeC.5406. This is in mild steel and is produced by folding and welding in a similar manner to the body brackets. We should be glad to know what the cost of such brackets will be as supplied to us from outside. It is hoped that by using mild steel in this construction it will be possible to obtain brackets sufficiently accurate so that we can dispense with the grinding operations on the two faces. The only way of proving this is to order say 1/2 dozen sets to be submitted for works inspection, and we should be glad if you will arrange this. The new type brackets will of course have to be tested out experimentally on 15,000 miles and/or the bumper test rig before they can be adopted on production. Owing to the excessive cost of the existing pieces we feel this is an item which should be treated with first urgency and put on the next available 15,000 miles test car. Rm.{William Robotham - Chief Engineer} One set has been fitted to 35EX for 15,000 mls test. Waller has been asked to watch for fractures. G.W. Hyman 11-1-37. T. Elmer. we should ask Let see 35EX.
