The Briley chokes, with shipping and 5 tubes, are around $550. 1959 is one of the best years for old supers. The gun originally came with a Browning marked Pachmayr pad. None of the 12 Gauge standard grade supers from the 50's have any collector value. At 95% the gun is probably worth around $1200 and the chokes add a little value, but not equal to the cost of the chokes. I would say the gun is worth around $1500 retail.
The 12 magnum from the 50's is almost identical with the trap model from the 50's except for the stock and forearm wood. Trap and magnum models were the only 50's guns catalogued with a 30" ventilated rib barrel.
