No Lothian Country vehicles are based from Central or Longstone anymore. During the lockdown there was one ECB vehicle stabled at Central overnight and the driver started their duty at Central, I have no idea if that still happens though.
There's some more pics floating about but I had this one saved to my phone from Google images (photographer unknown) of Stagecoach running out of Longstone.

As another topic of conversation - I read recently that Go North East are converting their euro 5 Volvo B5LHs to euro 6. As part of this they're removing the hybrid systems and coupling the existing engine (and I presume exhaust aftertreatment to get them up to euro 6) with conventional ZF gearboxes - I wonder if buses 1-10 will also have this treatment as part of their euro 6 upgrade?
