Until 2003, slatyford operated the majority of 12a/12b trips, which were single deck scanias running chapel house - fenham - walker - wallsend. Byker supplimented this with the 12, between west denton and walker. So entirely probable that you'll have travelled on a metrocentre liveried vehicle.
Service 100 has always been operated by slatyford.
