I see an arbor with a cutter, spacers, a vise, and even an original drawbar appears to be sticking out the back! Nice score! The arbors and drawbars are easily lost when the machines are stored and moved and sold, so it's really nice that you got them. I don't recognize the gear mounted to the end of the spindle in place of the drive dog, it must be a retrofit of some kind.
All this and your machine has the power feed for the table. Hope you enjoy!
