I will stick my neck out and guess that number is likely a "9" but perhaps you can post photos. As for manuals or a guide to help you get started I am biased but I think you would like my Metal Lathe Manuals CD that I have assembled. You can see details here:

As for parts, Clausing has some parts still but when I was looking for parts for my own lathe I got most of what I needed off ebay. Here is a page I use to watch what is on auction:
