by the way Fred,
Re your Electrolux Model R -- bottom row, 3rd or 4th one over, the white and gray one -- its cover is upside down! In all the illustrations in the instruction booklets for the S (to its left) and R, the cover is shown with the "pointy" end up and the "wider" end down. This has been upsetting me for hours now, ever since I spotted it! So would you please FIX IT! (hahahaha!!!)
