I have a friend who has an old straight-suction upright that he wants to sell.
I *believe* -- but am not *sure* -- that it's a Royal. It looks like one overall, has a single rear wheel, removeable nozzle to connect a hose and a blue bojack "To Fit Royal" bag. The serial number plate is on top of the fan housing. It's very dark and tarnished and hard to read but we could make out a model number which is 276.
Does that model number correspond to a Royal? It's not a Health-Mor as it has a handle switch.
If anyone is interested in this machine, call Ron at Boulevard Vacuum at 323-938-2661. I don't know how much he wants for it.
