The BF registration is from the latest DVLA 'age-related' issue of previously unused numbers. The two-letter/four-number format is issued exclusively to pre-1931 vehicles; the three-letter #XS series is being issued to post-1930 vehicles. If 9987 was issued in November, it seems likely that DVLA are now using another sequence of numbers for their pre-1931 re-registrations.
