The hubs I am thinking about for you is some of the SA 5 speeds. Peopel use the narrow ones on bromptons but also on other vintage bikes. I suggest you look at what is available and decide if you want one or two sprockets (if you go for two you could later do someting similar to what cycle_maven suggested and get ten gears) and if you want a coaster (or drum) brake or if you want to avoid spreading the frame and use your Weinman (or other) brakes.

Is it a 36 hole rim you have on the bike now (and are you using that or a similar rim)?
Yes, the rim is 36H.
Thanks for the link.
Both the SA SRF-5 (5speed) and the SA X-RF8(w) (8speed) will fit the bike without spreading the frame. The price is about the same (with a $30-40 difference) but I could not find a US seller the 5 speed so I have to add about $40 for shipping.
