Probably not, I apologize.I have been after one of those for years! Would you consider parting with it?
It's a re-brand of a Singer upright. Ryobi bought the Singer Manufacturing plant in Anderson SC and continued making Singer designs for Singer, Kenmore and other house brands. This is one such example. Ryobi used lousy plastics however and they tend to be very brittle and fragile as they age where older plastic body Singer made versions hold up much better.You find a lot of weird brands. I've never seen this one either but "durabilt" sounds familiar like I seen it on something before.
Singer Twin Fan models had beater bars.Those Ryobi uprights were HORRIBLE compared to other direct air uprights in the 90s. I knew a guy who had a Singer version of this machine, and it didn't perform well compared to a Hoover Elite I owned at the time.
One thing I find interesting about this Durabilt, though, is the brushroll. It looks like they were trying to imitate a beater-bar effect with the second row of bristles. Same as what Eureka and other brands did in the 50s and 60s.
