The breed information for RIW is correct. The single comb does make me wonder if he has what he thinks he has. The price is way high, as I said before. Wasn't sure what the OP meant by "pulling a fast one", though--the breed info, the price, etc?
How do you think this person is trying to pull a fast one? I don't see anything at first glance that appears untrue. The rooster is a bit pricey, but other than that
Here is a write-up on the RIW:
