Huckerby}14.3.40. ISOLATED PROPELLOR SHAFT BEARINGS. Results of experimental tests have indicated that it is imperative that all production B.V. cars should be fitted with isolated propellor shaft bearings before they are put in the hands of customers. Will you therefore please put in hand 12sets of parts to GCD.1481 in addition to the 6 sets you are already manufacturing for experimental cars. Will LA.{L. A.
