The description actually has the right years when it was made which means that the seller actually did some homework, so I don't think it was just a mistake. And the new ones don't look anything like the original. No, I think someone just got, shall we say, over-optimistic?. Heck, I've bought a never-used Sheridan Glenwood with the original tag and booklets for about a hundred dollars.
But who knows, maybe the seller will get lucky and find someone who absolutely HAS to have that bag and can afford the price.
