Guess for me--F,G These were simple,robust,quiet machines that did their job and well!Didn't know too many folks that had Electrolux.My Stepmom always wanted one-but got Sears instead.She hated my Dads Kirby.Its sort of weird-you don't see alot of 'luxes here.I do have a couple LX models and a tripleX-the woman who had the TripleX was about to dumpster it-glad I came along.Its in pretty good shape and has the on board tool holder,and the tools.Like its METAL dust brush and floor tools.The XL machines the bag ejector mechanisms are corroded beyond hope.The machines still work and pick up-got them at the swap shop where I get washers.
