I think the evidence points to the fact that what was called (or translated?) as “bell” was not indicative of the hand bell we see pictured in textbooks but was instead what we would call today a “buzzer” (at least where I am from – descriptors like this probably vary regionally). This does make a bit of a difference because whereas a bell of the type often pictured would make a fairly discrete sound (that would take some time to fade), both a metronome and a buzzer can sustain the stimulus presentation until the delivery of the US which would work better for the delay conditioning procedure where the onset of the CS precedes but continues until the delivery of the US.
