It should be remembered that the name "Darstaed" is simply the reuse of a distinguished name by its current owner although, unlike say "American Flyer [ by Lionel ]", the current production has nothing in common with that of the predecessor company.
The original Darstaed line was founded circa 1966 by Marcel Darphin of Switzerland, where the items were produced. In addition to a less known 'Scale' line primarily of Swiss and French prototypes, he produced excellent reproductions of the classic Maerklin "1941 series" 0 gauge coaching stock; further, he then produced models in the "1941 style" that Maerklin never made, most of which have become classics in their own right. The current company originally announced its intention to continue production of this type of car, but with each passing year that prospect has faded farther and farther from "the front burner".
So when you write just "Darstead" in the title you get the pulse rate of some of your readers elevated......
