I have a camera from… before that era (a cannon retina II from 1937-1939 that my grandfather used during the war), it has a textured film advance knob that’s super easy to use quickly. Someone skilled with their camera could probably get 3-4+ shots if they were prepared for it. If they had a camera with a film advance with the flip-up swivel knob, it could be considerably more.

I used mine for a photography course (everything about it still works flawlessly, just missing some powder coat paint from a couple places) and without much skill I could have managed maybe 2 myself - but analogue cameras were dying when I was growing up, the closest you’d usually come is those disposables or cheap plastic shell cameras, and you couldn’t do much with those. So totally different skillset than I was exposed to.
