Looking closer I can see that its a new machine, someone just hasn't set the date on the camera. Or maybe I should say an old machine in a new suit
I notice that there isn't the rethresher on the side of the 4th and 5th picture from the top, it looks a lot like the elevator setup on the 2588. Doing a little bit of zooming into the 2nd pic, it almost appears the the same shaker drive setup is there too, making me wonder if there are still bed augers. If the machine was still red it would make it a lot easier to look at!
From the looks of things, some of the stuff on this machine was a trade secret in 1978, but surely not anymore in 2007.
