It was agreed to test the gun on maximum recoil to see what latitude could be allowed before damage occurred. Having arranged the gun so that excessive recoil does no damage, it should be possible to work in such a position that failure to eject would not occur. Arrangements are being made to facilitate checking the pressure in the recuperator. Freezing tests have been carried out and a fluid has been obtained which gives excellent results at temperatures considerably below zero F.{Mr Friese} 3. SINGLE SHOT GUN MOUNTINGS. The L.M. & S. have full detail drawings of the drain-pipe mounting. The supply of ball bearings is assured and they expect to complete the proto-type in about one month. They have also details of the gear ring of the power driven mounting, and are putting the manufacture of this in hand. It was agreed that, as both these mountings might be considered to be development for the Air Ministry gun as well as the Admiralty gun, they should be charged to the Air Ministry number. 4. PRODUCTION OF SINGLE SHOT GUNS FOR THE ADMIRALTY. Elk. stated that though it was possible to locate quite a few machine tools in the hands of agents, these could only be allocated through the Inter-Service Committee and since the Navy were not prepared to release any for the 40 mm. gun job, no further action could be taken. - Continued - | ||
