Vintage - true, but that's some good gear right there... carried one of those rucks in DS/DS and had another issued to me in Okinawa in the late nineties. Still in demand, small builders like Tactical Tailor continue to build these or modify old ones. There's even a seamstress outside of Fayetteville, NC that modifies these "vintage" rucks for a select group of customers nearby. Still have my large, modified ALICE pack on the shelf in the basement CIF.
Like the Model 1911 .45 caliber pistol, it may be old, but it gets the job done quite elegantly.
