Rm{William Robotham - Chief Engineer}/Wym.{G. Harold Whyman - Experimental Manager} 640 WRAITH WATER DRAIN TAP. 26.G.VI car in France has a small copper pipe sweated into the drain cock (the latter having been bored out to receive it) passing through a hole in the undersheets, so that when the antifreeze solution is drained it can be caught in a receptacle instead of running all over the undersheet and being wasted. Will you please detail and instruct this feature for the 100 production Wraith chassis. There is no detail drawing for the pipe but Rm{William Robotham - Chief Engineer}/Std. can explain what hasbeen done. Rm{William Robotham - Chief Engineer}/Std. | ||
