The log file shows the auction was set up with a reserve. There is no way for anyone to add a reserve later - it is done from the server when the auction is created. I didn't see anything untoward but I have asked the auction owner to confirm that he saw the reserve. The reserve, or graphical R, is not shown on the front page - only in the auction listing and the headers.
The wayback archive shows the reserve sign - I've sent you the link.
