A Belvedere it looks alot like sharp or panasonic, a friend is emptying his mothers house and found in in her attic.He also gave me a Eureka and an oreck.
I have an 1121, looks more Panasonic like in the upper body, with the same nozzle. And they are related to Riccar in the same way Simplicity is. I'll need to get a better picture of it, but its the blue front/white back machine a vacuum or two behind the Panasonic Jet-Flo.
