I've just looked in Weaver's TV Video and Transmission Measuements (Marconi Instruments 2nd ed revised 1979). P31 shows a P&B graticule with 30% and 100% for video plus inverted 0%, 20%, 76%, 100% for demodulated video.
This book is a valuable reference for analogue era video measurements. Including the tangential method of measuring noise.
