It had a 10hp hence the "10"00 from the factory.
The 00 denotes it gear driven.
It's from the "Quietline" series.
Here is a link to the manual, should answer most of your basic questions.

And service manual

Most (maybe all?) attachments from Wide Frame Cubs will fit.
I'm guessing it's a 44 or 44A mower. 44" cutting width.
Show us some more pics when you get it and we might answer more
Edit:
I'd try to get the attachments too if they are of any interest to you. He's likely to sell them at a good price, since the tractor is sold.
