FO (Radnorshire) had, along with FP (Rutland), the slowest rate of registrations outside Scotland. Radnorshire was still issuing two-letter, four number registrations until the summer of 1958. The three-letter, three number series had barely got going when year suffix letters were introduced, so there must be plenty of *FOs still on the shelf at DVLA.
