This puzzle has proved to be far more difficult than I expected, I had found nothing about the model denomination in Denmark, I did find that the Dansk Scania Vabis cars were really German Der Dessauer, Type G3 8/24 made under license, so my first guess was that they used this model name, until I found the Bilhistorisk Tidsskrift 28/1971 and on the cover is the picture of the puzzle car Scania-Vabis SV3 Luksus-Torpedo-Limousin.
