The Moulton design was manufactured by Pashley as the APB, who then badged them for various companies
The frame was steel and heavier than any of the Moultn frames, but nevertheless an interesting and smooth ride for a small wheel bike. In this at least the Moulton pedigree shows.
Some are "seperable" rather than folding with bolt at the centre of the frame, dividing into two halves
I had one for many years, and if you do buy check the suspension is not sticking at the front as this is not something that many LBS will deal with.
The other thing is to ride it. The "space frame" means that the central frame is wide, which if you cycle "knock kneed" can be an issue
