Trot Salt - Carburation} FILE [Handwritten in a box] 2006 [Handwritten] Rm.{William Robotham - Chief Engineer}14/SW.9.2.41. Gliding Winch. We note that the RAF's requirements call for a 200 h.p. output from the P.111. We propose to give them a standard output to start with and in the meantime, should like Rm{William Robotham - Chief Engineer}/CTS.{C. Trot Salt - Carburation} to go through the P.111 bits in the Stores, and see if there are any induction systems, camshaft or high compression pistons, which might later be utilized to increase the power output of this engine.
