As requested we have reviewed the man hours necessary to complete the Winch. Below we shew how the hours and dates have been arrived at, the average week is 44 1/2 hrs. 4 Weeks work was done on the Winch Prior to the modifications required by the CLE. This represents approx. 1007 man hours. 40 weeks work is required to modify & complete the Winch = 1750 man hours. Total design hours = 2757 say 3.000 man hours Rm{William Robotham - Chief Engineer}/HH. requires twice as long as design = 6.000 man hrs. Total man hours = 9.000. Using 7 designers we should require to the end of July 1941 to complete the job as far as design is concerned. Using 7 draughtsmen they should finish by the end of August.
