Well, not only was this machine still for sale since a week ago, but the price was lowered to $75. I couldn't stop myself, went to take a look and brought home DP#96 for $65.
The model information tag is missing, but I believe it's a 103.0305. It's rough and missing only a few bits.
When I first saw the sellers photos, I could tell that there was something up with the spindle/chuck. There was too much spindle visible. I've got it apart already and discovered that a previous owner removed the thrust collar and reinstalled it upside down. That may be a challenge.

Ok, I removed the upper spindle collar and slid off the quill with bearings. I had to rig up spacers using a couple short pieces of angle iron, but the Jacobs wedges did the job and popped off the chuck. After I got it off, I wire-wheeled it a bit and discovered that it's a Supreme 5T chuck. I suspect that it was a little different than the oe Jacobs chuck and may explain why the thrust collar was reversed.
The pin for the thrust collar came out easy enough and the collar slid right off.

Well, I got the spindle apart and cleaned. I reinstalled the thrust collar correctly and loosely slipped on the chuck. The chuck fit correctly, so I have no idea what the po's motive was by reversing the collar.
Many other parts were cleaned.
Here's another first. The dog point of the pinion retaining screw appears to have been partially sheered off.
