Find a cox motor unexpectedly on eBay in boat search

The 2 boats on the left are Dumas SK Daddle Jr. I think the one on the right is a Dumas Short Stuff. Roddie could confirm that because he's got one. All are 18" boats. The other engines are OS .10 Marine. From the Dumas boats, you can't find any plans on internet and I think you cannot make a boat having only the Dumas plans.







Rediculous price? I don't know. The seller set his price on the high side together with the "make an offer" tag. Seen from the pictures, all 3 are complete with hardware. Maybe some have Octura parts? Many nitro powered boats sell for a lot more and are not in a better state.
