Electrolux
Great pictures above showing why the XXX is at the top of any list of 'Classics'.(Reply 14 has wrong dust brush & 17 has wrong crevice.)
The company date on XX seems to be 1940 that would put it at the end of the 'normal' pre WWII world.Production of appliances,cars,etc would have stopped by about 1942.We might guess that this was to start a choice of good and better models from Elux that would not be seen again until XXX & LX about 1952.When production resumed sales were forecast to be huge for consumer goods.It might have been easier for mass production to make what they knew best(XXX)and they seem to have sold to post war customers who did not ask for cheaper version.
On the branch rebuilt is anyone aware of original price,rebuild/replacement procedure,different owners manual,etc?At this time there would have been fewer branches but with many salesmen covering large areas with many sales.Some salesmen not close to branch would send contracts by mail and receive new vacs and supplies by bus(a common way to ship packages then). One long time branch in this region had 15 minute times for each salesman to turn in contracts and receive check for previous week before the next one stepped up to counter with a hand full of contracts.Back to the branch rebuilts the service dept then could probably do polishing and motor rebuilds as well as the later factory rebuilts.
