Those BBQ PARTS guys on Amazon are a bunch of clowns. I don't think they probably ever had any legitimate Weber warming racks. I ordered one from them and the picture was definitely OEM. What I got looked like the Napoleon but it's a piece of crap. I think it's just bare steel. Will probably start rusting from day one.
So I told them they sent the wrong thing. They said "oh we must have put the wrong item in by mistake" and offered a refund. I asked if they could just send the correct rack. What do you know, they don't have any left and the stock disappears from Amazon.
I haven't sent it back yet and noticed they had 8 more in stock earlier this week. I asked again if they could do an exchange. "Let me check inventory." What do you know, the 8 units all disappear again. No doubt in my mind, they are listing this as OEM which is incredibly rare and always $30 plus, then when people order, they send a cheap crap Napoleon which probably costs them $2. They hope the customer doesn't notice.
Think about it ... Weber hasn't sold this as retail since the MT came back, it's one of the exclusive perks of that grill. So where would the BBQ parts guys be getting them? They probably never had any in the first place.
If this happened to you guys too I would definitely not keep it, you got shafted. Stick it to these jerks, make them pay for a return and then kill their merchant rating.
