The guy answered they where not recasts "to his knowledge". Ha ha. The common phrase to say "i don't mind" if you want my opinion.
Games Workshop has a strong policy about recasts. They promise on their site they refund you for any bought that is a recast and they have done it as far as i know, after long discussions with the members of the CollectibleCitadel Yahoo group about this subject.
If the guy who bought the Winged Lancers is here and find they are recasts, i do council him to send them to GW for a full refund, and they will begin procedures with this seller.
