That is one of artist/designer David Gittens machines. He has been featured in the PRA magazine a couple of times over the years. That is David standing next to Dr. Bensen.
Whether his machines, and there were several, were honest attempts at creating a serious flying machine only David knows. However they are interesting exercises. Especially his open tractor gyro that more or less had the pilot in a standing position in a saddle like seat. I'm not sure if all of his machines actually flew. Or how well they flew. They sure had some of the 'sizzle' that Paul Bruty talks about. If they had anything else going for them then I would have thought that he would have secured a backer and produced a kit. But then again, maybe that wasn't his intent.
If I recall correctly, Don Parham knew David and if so maybe Don will jump in here ane give you more details.
