R.A.F. Instructional Notes on the Lewis Gun, 1918
Issued in April 1918 – the very month that the R.A.F. was founded out of the Royal Flying Corps – this booklet is an instructional manual on the use of the American-made Lewis Gun, which was fast becoming the standard British machine gun of the Great War – in the air as well as on the ground.
