It's hardly new, but the only vacuum I have in its original box is a Royal Prince 501 from the mid '80s. which is complete in its box, including all the paperwork; however, the box itself has seen better days. It was missing the dusting brush when I got it, but I found I had one on hand, left over from a little shop vac I used to have, that is identical to the original, except for a slightly different color—taupe instead of white.
In addition, I have a couple of Kirby tool kits, shampooers and a sander in their original boxes.
