First of all,
Welcome to the forums!
Unless you are looking for originality I would think that the hose and attatchments from most any comparably sized vacuum would be adaptable to fit your unit.
I would look around in some thrift stores for used ones even if you had to buy the whole vacuum to get what you wanted.
Also, you might check in the yellow pages under vacuum cleaners.
I'll bet a good dealer could help you out.
As far as the operating manual goes, I would keep an eye on Ebay for one.
Good Luck
