Here is a link to A1A Vacuum....they carry the "retro" or "classic" eureka vac....actually this is the cheapest I have seen it.
If you google "eureka 1934a" there are alot of places on the web that still sell these.......
I do really like Kyle's blue vinyl bag.....I have not seen the original cloth bags....If anyone has a pic, would love to see it.
