Thank you Donald, for a great answer. I wonder if other manufacturers followed right away. Can I expect to find a fresnel screen, for example, in any post-1950 Rolleiflex, Ikoflex, Flexarette...etc.?
I don't know in detail (I know about the Reflex II because it's my favorite TLR of all of them -- likely because it was the first one I owned, thirty-some years ago), but it pretty quickly became a selling point. There surely came a point, probably before the mid-1950s, after which you couldn't sell a top-end TLR without a bright screen, and before 1970 they were even in 35 mm SLRs (which, with faster lenses, needed them relatively less).
OTOH, I can tell you with confidence that no Argoflex E model had a bright screen (I've got an EF, the last one before they started dumbing down toward a model similar in function to a Duaflex) -- and with the f/4.5 lens, it could really have used one!
OTOH, I might suggest you can get an aftermarket bright screen to fit any of those TLRs you mentioned, if you don't mind spending money; the Beattie Intenscreen is said to be available for any 6x6 going, and if not, could probably be cut to fit from a larger one. You can get one for about the price of Yet Another Plain Ground Glass TLR.

I'm trying to ween myself of the trial and error method of camera buying. It's awefully expensive, which I wouldn't mind, except that I end up with a lot of okay cameras, rather than a few great cameras.
I go the other way -- probably because I can't begin to afford even one great camera, I've somehow gathered quite a flock of "surprisingly good cameras" -- like that Argoflex EF, which has a lens I'd categorize as "quite good for a triplet"; at f/12.5 (it's got the half-stop progression, for some reason) it's indistinguishable from a Tessar. Same is true of my Nettar, with its Novar-Anastigmat, just to pick a couple examples. The Anastar on my Reflex II, OTOH, is flatly superb, even wide open; I'd put it up against anything Rollei sold before 1950.
