I know Electrolux manufactured a 2100 series of vacuum cleaners, but I thought there were only three models: Hi-Tech, System 90, and Special Edition. Was there also just a 2100?
Were there different versions of each? Some have white on/off switches and some have blue. Also, some have PN-6Bs and some have PN-7Bs.
Following are a couple photos from eBay listings from an "Electrolux 2100" search:
