Sanitaire Blue Line Series Introduction?

[kirbyclassiciii]

May I ask if anybody here remembers exactly what year Sanitaire's "Blue Line" series of consumer-use vacuum cleaners came out?

I want to think it was 1983, which was the year they had their canned-ham canister model S440A. The first few uprights in the Blue Line were models S639 (same as commercial SC679 "Maid-Saver"), S644 (SC684), S646 (SC686) and S648 (SC688).

Ben,

As Sanitaire rarely advertised in newspapers, I was unable to locate anything to verify the start of its blue professional line.

1980s hospitality industry or home maintenance trade journal and catalog advertisements and articles likely have the information. You may be able to access digitized copies or request hard copies at worldcat.org or other sources through your local library.

Paul,

Another way to date these Sanitaires would be to look at their nameplates.

If the nameplate is both black and silver, then it will date from 1985 or earlier.

(the example nameplate is from an S440A; this example dates to 1983-85)

But if the nameplate is primarily silver, with black text, then it will date from 1986 or later.
