I just got a rainbow d2 from a estate sale yesterday.I only find vacuums at estate sales. There is also a elextrolux rug washer for a silverado like the one I already have.It also has the attachment carrie and the wands also the box that the wands came in and the manual also the manual for the rug washer.I really havent had a chance to look it over but it looks preety good for the age.I hope to post some pix soon.Is there any test I can run on it.I am going to try the steel wieght test like the salesman did for electroluxs when they were demonstrating.If there are any other test please tell me. vacuumwomen
