I don't think you get that dorsal without another species figuring in, lawrenceanum, maybe barbatum or callosum. I suppose anything could happen if a species is selectively bred for a dozen generations, but then I would hope the overall flower quality would be much more impressive than this.
NYEric suggested buying it if it isn't outrageously expensive, but unless I was desperate for a Paph, any Paph, I'm not sure I'd take it if it was free.
