In general terms, earlier are more likely to be flexy BUT there's a lot of variation. I've got a 1940s cheapie that's got as much flex as a slightly disappointing 12 (early 1920s), and a 52 1/2 V made somewhere in between that's flexier than either. All with #2 points, too.
There's a thread in the general topics forum pondering H.P. Lovecraft's pens which includes an anecdote about him spending an age selecting a new pen (the pen store counter buried under piles of pens in the "rejected" and "possible" camps). It's probably because there's so much individual variation in the points, each one hand made of course, that the Son of Providence had so much trouble finding one that suited.
I can truly understand Lovecraft's actions, flexible nibs seem to hold some mysterious set of unknowns that one can only see through exploration in the trenches, hence it would appear I need to make it to a pen show or two to engage in some test drives of my own.

I've had great luck with Canadian Waterman's nibs from the '40s. They're no wet noodles, but they have a fair amount of flex without too much pressure.
Depending on how much you're looking to spend, I'd keep an eye out for a Skywriter, Junior, 3V or 32V. I have a few different versions of all of these and all are quite flexy. Of course, all nibs will be different and if they've been replaced then who knows, but in general these are inexpensive pens ($20-$40) with flexible nibs. For what it's worth, my Canadian Skywriter is very flexible but is also quite broad and wet to start with, whereas my Junior is very fine but can flex quite well.
See
this thread for writing samples from my Junior and 3V. Those were written with slight/moderate pressure but not much extra effort or change to writing style.
Wow, you're not kidding, that 3V seems to be on the right track. Very Nice!
