I seem to remember that that doctrine was that of Sir Frederick and not Avro.
HP reckoned to be able to build the Victor with a largely semi-skilled labour force. Allegedly a wing former would have 4 accurate master holes drilled by skilled labour the the hired help would then add the rest.
When BAe prepared new wing mods for the Victor K2 they used one aircraft as a template and produced 21 sets of kit that would fit only one aircraft.
Mind you I understood the Nimrod was no example of identically machined parts either.
The Vulcan had an offset doppler bay. A doppler aerial alignment required knowledge of the aircraft's fore and aft axis which was determined using the compass swing rods and a Watt's Datum Compass. A line normal to the fore-aft axis was then determined by spotting the Watt's datum on this axis, under the aircraft, and swinging the Watt's Datum head through 90 deg.
A point was then measured along the normal at a precise distance of 15 foot 4 and a quarter inches (IIRC) plus or minus a bit. The plus or minus was the known variation from the standard for a particular airframe. Clearly manufacture in those days was more measure with a micrometer, mark it with chalk, cut it with an axe.
When we changed from Green Satin to the solid state DD72M it was a fit and align once and forget.
Any errors in this are due to anno dominii as it was over 40 years ago.
