SBS586 on svc 74 yesterday. This joker is a JB MKIII with "sv
66" scribbled besides the bus stopping sign. Driver is from the
atlantean B10M, SBS2650. Think SBS is maintaining tt bus.
As far as i know of, JB Mk IIIs are very rare on svc 74, although
74 is half controlled by BBDEP. All others are the repainted
variety.
