Thank you for the kind words, but please go ahead and unlock the question.
Postwar busses are not in my normal field of research and I really have no idea where to look.
Based on my passion for wheeled military vehicles 1935/1945, which can at times be more difficult than a passion for civilian vehicles, I often dig very deeply for clues as I did here.
In any case, as I said earlier, Hiawatha is doing very well and seems to have a lot of knowledge of post 1945 vehicles so if he can finish the question, all the better.
