The Eureka Model 1099-A is similar in styling and features as the Model 1100-A Empress that debuted in 1965. Model numbers were not always given in consecutive order, so it's hard to say if the former or latter was manufactured first, or if they were produced concurrently. One difference may have been motor amps (the 1100-A was rated at 7.7 & the peak horse power at 2 1/4). Another may have been the attachment set. In any event, that's a classic Eureka from the seafoam blue canister era of the '60s & early '70s. Congrats on your grad gift & HVAC school graduation & thanks for posting! P.S. An old vac shop tip from back in the day is to dust the cord with talcum powder to aid the Cordaway's performance.
One of my grandmother's had a similar model to this vacuum cleaner, I believe it was called the Empress 2. Your cat is cute and you did an amazing job!
