i'm pretty bust at the moment, but i'll see what i can do. in the meantime, if you want a chance to find out for yourself, there's actually an orchestron listed on ebay this week- an extremely rare occurance. i think it's only the 2nd or 3rd one i've seen on ebay, and in the rare chassis design too... kraftwerk had the original, more common wood-grain model. it's item #290157002758.
