I just purchased a wonder Kirby model 516 on Goodwill auctions on 4/26/12 The machine and all accessories appear to be in VGC in viewing the listing photos.
My great find cost me all of $21.00 + S&H $32.00. The machine itself and all attachments are original, with the exception of the cloth bag on the machine.
Hopefully the machine will be delivered within the next few days.
This model had a gray cloth bag with the name Kirby in red lettering centered in a circle. I'm trying to locate a replacement bag like this in order to keep the machine as in original condition as possible.
If anyone has a used, or NOS cloth bag for a Kirby model 516 PLEASE contact me.
