Looks more like one of them '64 8Ns to me. We had a guy in Missouri trying to sell a a 9N as 8N. He said since it looked like the 8N he use to own so that was what it was despite repeated emails telling him what it was. He did finally change his ad and it is still for sell.
I wouldn't worry with flagging the guy. If someone is seeing it on CL they have a computer and should do the research before shelling out the money for it.
You see this all the time. It gets funny at times.
