Thanks for information about Ikarus-415/435.

There is a photo of Ik-435 (1985) near Ikarus factory in http://www.edigital.hu/Szakkonyvek/Gerlei_Tamas_-_Kukla_Laszlo_-_Lovasz_Gyorgy_dr._-_Rolling_Legends_-_The_history_of_Ikarus_Works-p144389.html book, but it has different colour: silver or grey with orange stripe (page 174 of English version book).

Is it the same bus, and it was re-painted different colour? If yes, in which year?
