Other Production Year Clues
Something I noticed when looking through Eureka ads is that the switch was gradual - maybe starting with store signage, then literature, bags, and decals/stamps. For example, the 1986 italicized block logotype was not featured on cleaners until 1989. Also, the advertising departments sometimes used previous logotypes as I saw in one 1986 ad with the 1966 E/W logo & logotype. (The first photo is of a 1988 advertisement and the second is from 1989).
Corrections/Additions welcome.
1. Eureka switched to the plastic base in 1975.
2. Hood vents were added in 1976.
3. The E/W logo (with logotype), was first used on the Golden Crown Roto-Matic in 1957; beginning in 1966 the E/W and logotype were used on all cleaners.
4. Eureka changed to plastic handles in 1983.
5. The new style hood with narrower motor cap debuted in late 1987 on the model 1432. Other models in the 1991 catalog with this style were: 1435, 1442, 1485, 1923, and 1967
