Dennis Javelin, Your mystery bus at ■■■■■■■ Classic Coaches is a Commer Comander, Reg CMS 9 new circa 1946 to David Lawson, Kirkentilloch, then to Highland Omnibuses. Next owner was Mansie (Magnus) Spence St Margarets Hope,Orkney moved on to Jim Harvie, Evie and lastly to David Laughton, Deerness Orkney. out of service in 1977 it was bought by Harvey Sutherland where it was transported down to Aberdeen on a Seddon Atkinson 8 wheeler owned by J & S Mackie, Tankerness, Orkney. I think Will Hamer acquired it from there. Scottish Aviation bodywork. Ther was another identical Commer body uses as a green house at Mirfield, Deerness which I remember seeing on a visit circa 1997.
Cheers, Leyland 600
I don’t know how I missed your (definitive) response, but I’ve caught up now 
It was the bodywork that confused me - I knew it wasn’t Duple and Plaxton wasn’t a good fit either. Then again, I’d never heard of Scottish Aviation until now.
Eee, things yer learn on t’ internet.
