Here's  73.47 from my 1980 copy of the rules (from the GPO). I first ran an
audio  proof in 1970 or 1971, and I think these were the rules at that
time. Prior  to that, though, they may have gone down to 30Hz. Interesting
typo is  printed in paragraph (b) regarding where the report is to be
retained and  how long...

I am talking about the 1960's.....I believe you had measure response down  to 
30 cycles in those days.  I seem to think that distortion may not have  been 
required.   My brain may be full of cobwebs but I seem to  remember having to 
go down to 30 Hz.
