Later, inside the French Embassy, the same VZ 61 Skorpion is seen without the olive sling attached.

Though the OPEC raid took place in December, there is no snow on the ground in Vienna, and there are green leaves on the trees when the raiders disembark from the tram.

At the end of Part 1, Carlos and his men are waiting at a tram station in Vienna. Behind them is a red sign that says "Kebab and Schnitzel". Kebab was not introduced in Austria until the mid nineties.

As the terrorists are waiting for the tram before the 1975 OPEC raid, a sign for a kebab stand is visible. Vienna's first kebab stand opened in 1983.
