This setup will work for stock Brompton 2 speed or 6 speed (3x2 BWR hub made by Sturmey Archer). But since every hub has a little bit of manufacturing variance on the free hub body you may also need to match with a different snap ring circlip (either 1.2mm, 1.5mm, 1.8mm and 2.2mm) + free hub spacer washer.
