Very nice little bare-bones cleaner for the time.That 70's tangerine color is timeless. That is so cool you ave the original paperwork too 
It looks like Mr. Manning is still alive and well in Clovis, and he was only 27 when he bought that vacuum. Amazing!
Companies always went into so much detail back then too on the design of the cleaner and why it was made the way it was and what all the little features are, fun to read the sales pitch.
I have the later or last version of this model they made way out into the 1990's with a powernozzle, called the "Ironsides". Sadly no powernozzle was with it when I got it.
They are good sturdy little vacuums and this one was so well kept too.
