VD was fully issued at the time - it ran from 1930 to 1938 - so is not available for age-related status. DS ran from 1903 to 1962, at which time they had reached around 5,500, so unissued subsequent numbers could be allocated to the age-related scheme. BF and WC were never issued in period so the full sequence is/was available.
