This is a replica of the blind issued to New Cross for use from 14.10.89
A change of policy seems to have started from this date when the night bus blinds were white on black instead of yellow on black.
There were 3 groups to minimise blind length - the length was 56' 10" . The groups were (1) 1 - 36 - 141 - 171 - N47 (2) 21 - 53 - 89 - N53 - N72 - N77 - N82 (3) 12 - 176 - 184 - P3 and these groups were usually seperated by a blank white blind which I would imagine would serve two purposes - (1) the driver would know when he came to end of his group and also a new display could be stuck over the blank in case of a new turning point being added
