Congrats on nabbing such an awesome vintage Eureka—looks stunning with no noticeable scratches and the original bag jacket!
The Eureka Model 2070 debuted in 1969 in Ivory & Lagoon Blue Types A, B, & C (Canadian). In 1971 the color combo changed to Fawn Beige & Moss Green for Types D, E, & F. The model was discontinued circa 1975.
Look on the bottom for a protruding nub. Sometimes Eureka put digits around it to indicate the exact period of production.
Euphoric Eurekaing!
