| By/RD. from Rm{William Robotham - Chief Engineer}/Wst. c. Da.{Bernard Day - Chassis Design} 6089 Rm{William Robotham - Chief Engineer}/Wst.15/AP.9.4.37 Instrument Lamp Bulb Holder to RR.Sch.1041 The lamp holders which have been made up to the above are not satisfactory as the single thread provided is not adequate for holding the bulb correctly. We are sending one of these to you herewith for your inspection. We should like this design modifying as soon as possible as it is now holding up the completion of the new instrument board. There are probably several varieties of screwed adaptors on the market which could be adapted for this purpose. Rm{William Robotham - Chief Engineer}/Wst. | ||
