I've seen photos of a Gramophone Company truck outside the Leeds  Cathedral 
when HMV recorded Elgar and perhaps others there, live, around  1927/28. 
The truck was identified on its side as the "Gramophone Company/His  Master's 
Voice."

Actually the Gramophone Company in the U.K. started doing recording from
a "lorry" -- meaning a truck -- VERY early on in electrical recording. 
Ernst Lough & Temple Choir "Hear My Prayer" was a HUGE hit recorded in
that lorry.  The Melba Farewell and Chaliapin concerts likewise. And the
Chaliapin concert seems to have been recorded in accidental stereo.
