You can be sure...
If you get a restored Hoover/Kirby from Marty, it will be a fresh as it was when it was new. His restorations are meticulous! He has done work for me on several Hoovers, and they come back like new. When he restored my 634, he couldn't stand to let it come back to me with the replacement bag that was on it, so he sewed me a new one in gorgeous matching fabric, embroidering the Hoover letters on the front and the Hoover circle logo on the back. I about fainted when I went to pick it up, as it was a surprise addition for my birthday/Christmas present. He is truly a Hoover guru if there ever was one.
