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 1986 or earlier.

(the example nameplate is from an S440A; this example dates to 1983-86)

But if the nameplate is primarily silver, with black text, then it will date from 1987 or later.

Thanks, Ben. A former Eureka executive relayed to me that the nameplates were outsourced when he joined the company in 1978 and were later made by Eureka. I imagine the computerized version is the latter; although I always thought that the change occurred in the late 1980s. Good to know.

Paul,

I changed the start and end dates of the nameplates. I believe 1987 was when they switched over to the computerized version.

Why? I spotted a 1986 SC684D and it still had the older nameplate design.

Thanks for the update, Ben. 1987 is closer to my guess of 1989. I know that Hoover changed its serial number format around 1987, so I thought Eureka followed suit a year or two later. Although it may be that both were apprised of the software around the same time.

I do hope you'll locate some old periodicals and catalogs which will provide a timeline of model introductions, including the start of the blue industrial line.

Yes, Paul, and I also found a Eureka Express 8285B canister which also had the older nameplate design.
