Folding receiver hitch mounted rear step, Anyone seen these?

At first I too thought that was hand made. I have made a few like that myself. That however has a sticker with the manufacturer and model # The # is w 9744. I can almost make out the other information. If I had a magnifier I think I could get enough to do a search. Maybe the sticker is for auction but it sure looks more official. If you you want 5 I would think a good fab shop could build them for the offer. The trouble is liability. I would check west marine, e trailer, search folding step.
