How an aeroplane is built
A 1918 aircraft-construction manual by Stepney Blakeney, published in London by the "Aeroplane" & General Publishing Co. for wartime workshop hands and apprentices building wooden airframes. The line drawings show jigs, clamps, drilling fixtures, longerons and sheet-metal fittings in plain outline, often with call-out labels and dashed hidden lines useful as technical-diagram vocabulary.
