Of course I didn't mean it literally.
Anyway: there is one integral (Berlin Classics), recorded in the sixties, and played by several organists on (mostly) non-restored Silbermann organs, though some of them had temperament changes and electricity was available.
But I guess the sound they make is less 'original' than most of them sound now, after restoration.
Old instruments have to be restored and taken caren of. And the slightest changes can influence the overall sound, no doubt about it.
(And of course in many cases the tuning and temperament have changed in the 19th & 20th century, too.)
But there are still instruments where ordinary people are pumping the bellows in concert. For instance: last spring I was in Noordwolde, Groningen (Netherlands). In the village church there's a 17th century (restored) Huisz-organ (2 manuals + pedals) with original bellows, and they are still used in concerts and recording sessions. So: no electricity there.
Al Gore would be very pleased.
