Almost as soon as I had asked the question I found one myself in a copy of
Holdsworth's "Aid to Happy Cycling" for 1936. Quoted verbatim from Page 74 _
"CAMPAGNOLO Front 23/3 Rear 27/3 Pair 49/- These Campagnolo Hubs are
THE GOODS for racing. Just a twist of a lever on one side, and wheel is
freed" So 3 years after Tullio developed the Q/R Hub they were exporting
to the UK.
