Coverley - Production Engineer}/JWW. 1202. Rm{William Robotham - Chief Engineer}9/R.12.4.38. With reference to the query the other day as to which pieces on the Wraith were sufficiently stabilised to justify dies being put in hand for die casting, we have gone through the list and have separated it into two sections, one the parts released, the other of dies which should be held up. In cases where dies are held up it does not mean that the part should not be manufactured, but that if it is necessary to make the pieces they should be made of sand castings as there is the possibility of the design being altered.
