| Rm.{William Robotham - Chief Engineer} Gunn 5 Lp.{Mr Lappin}14/JL. 23. 7. 40. The following is an extract from a letter received from Mr. Frise :- "Whilst they are doing the firing, I should like them to kill two birds with one stone and test the possibilities of firing through a blast tube, such as we shall have to have in the "Beaufighter" installation. You could borrow one from the machines at Hucknall if you like, but I should imagine you will want something slightly bigger in diameter. At any rate, I am all for settling points like this as early as we can, as it prevents hold-ups in the installation at a later date." Lp.{Mr Lappin} | ||
