While the best vintage folder is probably a Raleigh Twenty, I don't think any vintage folder is really a very good folder. The Raleigh Twenty's saving grace is that it's a good bike. A taller person may need a longer seatpost for it (28.6 mm) but that's no problem.
But it's better do discuss them in the folding bikes forum... more folding bike expertise there.
