So, at least for Simplex, I don't think the tooth spread is a significant problem. On the Simplex, however, the range of movement is limited by the fact that the design has the inner travel of the top of the rod stopped agianst the right side of the seattube, so I don't think this design can shift a triple.
I have an Italian made Simplex suicide shifter from the 1950s I got off
eBay a couple of years ago that has a shorter cage than most of the ones
I've seen, so it may not shift such a large difference, but then, a
difference of less than 10 teeth was more common back then. Also, this
one doesn't have a stop on the lever like most of the ones you see, but
I doubt that's so it could shift a triple, just an early non-index design.
