Measurement of trunnion load. To be carried out as soon as Mst/Shaw has completed his apparatus. This might with advantage be carried out concurrently with the barrel temperature tests. Gun No. 11240. To be re-assembled immediately to specification Ve/NP.7/CB. 13.8.40, with automatic magazine. The gun to be mounted on its side as in the Beaufighter.
