Tho I did find an SPD which as Sub Branding for the 150 (60 before it was renumbered) https://www.flickr.com/photos/stagecoach...Vu-2nf2zkC

It was later repainted into Doxford Clipper (something I did find out that 39A went via Durham Road if anyone has a map of that it would be appreciated I would be intrested in the route it went), then Venture then East Durham

No it wasn't - Drifter was introduced in 2007.
See here for photo of the same vehicle, still in corporate livery, in 2006... https://www.flickr.com/photos/andyburbid...YSi-7s6VDG

Re 150, several routes had that form of sub branding applied to fleet livery (as well as various other forms of sub branding over the years).  2006 was when the step change was made from sub branding to full on multicolour designs.
