The Eureka Model 1279-D/Model 1234 Roto-Matic Power Team was manufactured circa 1980-81 as the Model 1279-A was launched in 1978. Others in the Brandywine and White color scheme at the time were the models 1273 (8.5 amps), 1275 Cordaway, 1289 (11.8 amps-Canadian?), & the 1290 (11.5 amps). Differences besides amps may have been lit or unlit pn, attachment set, & Cordaway or wrap. There were also the same colored canister models (non-PT) & uprights with varying features. Anyway, Dave & Mike gave you an awesome vintage Eureka for your collection! Great upload - thanks!
