| To E {Mr Elliott - Chief Engineer} /Da. {Bernard Day - Chassis Design} from Rm {William Robotham - Chief Engineer} /Std. c. to E {Mr Elliott - Chief Engineer} /Jnr. {Charles L. Jenner} 440. 200B Rm {William Robotham - Chief Engineer} /Std.3/AP.10.7.37 As requested verbally by E {Mr Elliott - Chief Engineer} /Jnr. {Charles L. Jenner} we send you herewith Rm. {William Robotham - Chief Engineer} 412 which shows the water thermostat scheme which we recommend for Bentley III with dummy radiator shutters. We have tested scheme Rm. {William Robotham - Chief Engineer} 415 (attached) and this is successful except that it indicates a need for a larger bypass pipe - Rm. {William Robotham - Chief Engineer} 412 provides this and dispenses with the hotspot connecting pipe and banjos. We are having the necessary parts for scheme Rm. {William Robotham - Chief Engineer} 412 made and will test same as soon as possible. Rm {William Robotham - Chief Engineer} /Std. | ||
