I thought you guys would like it. To my knowledge there were less than half a dozen of this particular prototype built, but that's just the rumor I heard from the guy I got it from. I also know that one has been scrapped for the Aluminum. There is no sticker on the bottom and no place to put a sticker. The only thing on the bottom is an hour meter and a gauge to measure how many passes you've made. It works perfectly and actually cleans very well, at least as good as any Kirby Generation. When I took the pictures I also took a picture of the bottom but I couldn't get my point and shoot to focus so I took it with my Blackberry, now I can't get my Blackberry to sync so I have e-mailed it to myself from my Blackberry and it is taking forever to receive the e-mail. As soon as I get the e-mail from myself, I will post the pic of the bottom.
