Hi Gary & Brian,
The Golden Crown was produced from February 1957 to September 1961 in two successive models: 960 & 960-A (Brian, there was no anniversary model Model 960-B; the ad that I posted in another thread was a typo according to Eureka's shipping record).
I did some database digging for print ads to construct a timeline of Eureka vacuum cleaner hoses. I also perused patents but was unable to find any assigned to Eureka Williams or Eureka for vacuum cleaner hoses, so they must have been outsourced. Brian, do you have any information?
Eureka Hose Type Timeline
Pre-1956: fabric (not sure when an attachment hose was first produced for uprights; first Eureka tank-type 1941)
1956-61: vinyl
1958-74: "unbreakable" ("nylon" used in ads beginning in 1960; these two terms seem to refer to the same type as some ads included both terms together)
1971: vinyl reintroduced
Eureka Williams apparently discontinued using the vinyl hoses for its canisters after 1961. They were brought back in 1971 with the launch of the Sweet Sixteen (1600) Series canisters.
The company prided itself on its ever-expanding customer options, so some Golden Crowns may have been originally sold with nylon hoses or they may have been replacements of the vinyl ones. The same theory may also be applied to some having a separate curved wand like the so-called canned ham tool sets.
Gary, regarding the inverted triangle with the E/W logo on your blue canister, the logo was introduced in 1957, but in the '50s, '60s, & '70s Eureka used several logos and logotypes on cleaners concurrently either because it retained the original over the years, or possibly as some type of indicator. The lagoon blue & white color line was launched in 1961 and would at some point include Model-Types 980-A,-B, 806-A-B, 880-A, 910-B-A, 912-A & 948-A—at least three sported an alternate to the E/W logo.
Attached are photos of some ads that mention each type of hose along with some showing the rug tool with the integrated curved wand that Brian mentioned. In addition I included some representations of the blue & white canisters I referenced.
