I found mine....
at a Goodwill auction. I was the highest bidder, was not there when the auction took place. I got the call and "flew" down to get it. The manager told me after the auction, a guy came by and really wanted it, but they saved it for me.
I pretty much got what you did but also a new package of the blue Electrolux bags.
I did not get the insert to allow for wet pick up. I also think there was a wider no-electric floor brush.
As yours it is in such great shape, it could have been in the original box. Did you ask for it?
Great score!
