This is fun!!!
You can also add Eureka’s “Christian Klingspor” Signature Series of vacuums. Klingspor was a famous Swedish designer and parent company Electrolux SE from Sweden seemed to think that putting his name on some Eureka models would be a good thing to do. These were mostly hard bodied Bravo uprights from the early 1990’s, but there was even a CK edition of the compact Mighty Mite II canister. Not sure of the model numbers though.
I guess these could get the CK code? Calvin Klein?
