Daniel : The JEP loco's are neat and I have not seen them before except in some book pictures. I like the little ones myself, because it think it likely that because they were cheaper, Mom & Dad are more likely to have purchased them for their children and hence they were really played with...so have a history. Thanks for sharing.
OBTW I just purchased the new book "Hornby Trains in France" by Chris Graebe. If you have not seen it you should take a look, the pictures are beautiful, full color, etc and complete with a reasonable history of when they were manufactured. I found my copy on e-bay from Chris himself and it came with a signed memo!
Best wishes
Don
