ELECTROLUX about 1935
Hello Barbara. OK, your (son's) Lux is actually newer than that. Since it has the (now painted)chrome rear end, it is later than the original issue of the Model 30, which debuted in 1937 and ran two or three years. It has FLAT runners, so it is pre-1948. I would put this machine around 40-41 (there was a moratorium on the manufacture of these during the war years of '42-'45.) Without more info, I cannot rule out '46-'47, either. However, the good news is this DOES accept the far more common 30/XXX cord, as well as MANY common coffee percolator cords, especially from the 50's and 60's. Also, most any half-way decent vacuum shop (good luck tryiing to find a REAL Vac Shop!) will have a cord for this, preferably a used one! If the bearings are good, and the carbon brushes are replaced as needed (about every 20 years!) and assuming it is kept away from water, it will probably last another 40 years! The 30/XXX (different designations along its history) are nearly indestructable and very well designed. With any luck, hoses and bags will likely continue to be available for the rest of our lifetimes! I hope your son enjoys the vacuum, it is a great machine to take apart and learn on, just like an Erector Set!! Best of luck, Rick.
