Info on this DE 10

[Super]

I rarely see this neat DE 10 come up anywhere and I often wondered where it came from. Was it a Limited Edition or part of a special set? Might it be a replica of a real JR engine? I really like the coloring except for the yellow wheels as black or gray would be nice. I also like the large gray vent panels on the side/front. Does anyone recognize it and can shed some light on it?
