I've been watching that NIB 1499 MK-II on GunBroker. An average 1400 MK-II is probably a $300 gun at best today. The NIB is nice but I'm not a collector and if I bought it, it would quickly not be NIB and unfired so I'm not sure what premium to pay. The seller says the guns weighs just 6 lbs. The current auction is the 4th. The first time around the max bid was $400, 2nd time it was $500 and this last time it was $575. I'm only interested in it because of it's uniqueness, not because it's a great shotgun. Not many of those old Winchesters around.
