Carey- many thanks, very interesting stuff!
And here's another Elektoy trivia item- one of the things that catches your eye about the Elektoy cars are the unique trucks. I was looking at the stamped side frames thinking that they looked like they were made to have springs installed, but none of the cars in my set have them. Looking at other photos however, I see that a few cars do have truck springs. For example, see the hopper car in the photo below, and also the photo from the Toy Train Museum posted earlier. The springs were just decorative and no doubt were easily lost.
