Note the flying saucer at the front fuselage. Every last aircraft of a series will get a marking like this. The last Mirages IIIRS for example has an owl called Mata Hari at the nose.

Note the little green cougar behind the cockpit! This figure is painted, because this helicopter is the last from all the Super Puma / Cougar helicopters in Switzerland. Swiss tradition.
