Vintage Playmobil System LUFTHANSA AIRPORT VAN VEHICLE Klicky 1970s Incomplete

Vintage Playmobil System LUFTHANSA AIRPORT VAN VEHICLE Klicky 1970s Incomplete. There are marks that look like marker in a few places. The inside of the top piece has white residue that I couldn’t wipe off. The bottom piece had quite a lot of dust inside its crevices when I received it, but I was able to wipe a lot of it off (although some remains). Thanks! Item is in FAIR condition.
