7 legged sofa ???? What, who, when??

I am trying to find out what type of sofa, where it might have come from, and who might of made this sofa. I have had many people interested in buying this sofa but do not have the slightest idea of how to price it. I have spent over 100 hours researching it and can not find a single sofa with the 5 front legs and one cushion anywhere. The sofa was bought at and estate auction as a chipendale sofa and given to us as a gift. I have many photos.

Thank You for reading and I hope to find out what it is.
