Craftsman 10'' Table Saw - Model No. ?

Got this table saw for free. It took 2 weeks to remove the rust and free the adjusting mechanisms. Now it runs like a champ.
It is a direct drive.

The only problem I see is that the shaft of the motor, when I turn it, I could see a slight wobble. Doesn't seem to affect the quality of cuts. I am wondering if I could pull the shaft out and replace it - is that possible?

I do not know the model number of the saw - it is nowhere to be found. I would love it if someone could tell me the model number and perhaps how old it is.

It is direct drive, stamped steel extension wings, micro-adjust fence. I am including some pics.

Thanks,
Tom.
