Interesting, Bud. That Universal stick-vac can really transform itself!
Update: I stand corrected about the origins of this Oreck design. According to their website, Dave was working for RCA in the early 1960’s when RCA had started to manufacture this kind of lightweight upright way down in New Orleans. Oreck took over the failing venture in 1963.
Somehow the design ended up in Europe by 1970 - maybe McDonald Electric bought the European rights from Oreck to make and sell this design in Europe.
