Very nice! I have one just like this that I am cleaning up and sending to my sister in Atlanta.
Regarding the hose, I agree that eBay is a good source. Is your Super J for your collection or do you plan to use it as your regular vacuum? I've seen some of the original, braided Super J hoses on eBay as well. You just have to check the condition of them, especially at the junctions.
Good luck!
