Yes indeed, all original right down to the hose & cord.
The Constellation was first introduced in 1954 with the two-tone blue 82. From 1955-57 the Mulberry 84 and Heather Rose 85 were added to the lineup and all three ran concurrently. The 84 & 85 were the first floating models.
The Canadian version of the 84 was called the 841E and came with the regular rug/floor nozzle. Mine also has the wide wall/bare floors brush and I have no doubt the USA version had that too - fairly easy to find to make this set 100%.
The one you've pictured has the much desired wheeled floor nozzle. To come across a swiveltop Connie with all that paperwork and caddy, in the original box, is a thrilling rarity. If I didn't already have my 841E in similar condition - and the shipping wasn't US$86 to Canada - the ebay one in Denver would be Buy-It-Nowed already.
