| O {Mr Oldham} /NOTE Ve. From Rm. {William Robotham - Chief Engineer} G. {Mr Griffiths - Chief Accountant / Mr Gnapp} Ev. {Ivan Evernden - coachwork} Derby copy to: I sent Frise a copy of the installation drawings for the 40 mm. in the Beaufighter, and asked him to let us have any comments. I attach a copy of the reply I have had from him. I suggest that you let Bristol's turret man examine the half inch gun independently of a visit to see the 40 mm. mounting as the Beaufighter installation may not be ready for a few weeks. Rm. {William Robotham - Chief Engineer} Drawings. 92886 and 93554 attached to Ev {Ivan Evernden - coachwork} 's copy. Chatterton Re Chassis No Date | ||
