The sticker on the seatube that says "Direct Drive Prestige". Also weigh your fork, if it is Prestige it should come in the low-mid 700 gram range. My understanding is some of the earlier Stumpy's were prestige but not branded as Specialized did not want to pay the license fees for the right to sticker them. Yours is definitely Prestige and a nice oversize version of it. Hang onto the at bike, it's the best of the steel Stumpy's IMO.
