Hi. I need some info from you Electrolux experts out there. I found a beautiful Model E tank, all original (except for hose) in a thrift store this weekend. It has the combination dusting brush/upholstery brush attachment in gray, but the rug nozzle and floor brush are the style used by the later Model 30s and the 60s. I seem to recall being told that the very early Model Es had these tools and that the combination floor tool began later (perhaps when the AE made it's debut). Also, the plastic "stabilizers" on the front wheel are missing, and I think that they, too, came later. Am I right about any of this? Can anyone tell me the timeline of E and AE production? Thanks.
