My Apple IIe box has labels telling me that it shipped via the Netherlands, where Apple had their European offices at the time. Later Apple imports had licence agreements in the Dutch language (not sure about Apple II family or pre-1984 without crawling in the attic).
Maybe Flemish Belgians were buying loads of Apples too
During the 1980s, the London based market research company for whom I worked used the Europlus, IIe and IIc for computer aided interviews in the Netherlands, France, UK, Germany, Sweden and a few other countries. The Apple II family was used widely in Europe when people could afford to buy.
