Just got back from a local gun show and a gentleman was walking around with a 20 ga. 00 grade fw, 2 barrel set with matching forends, not a collector but a sound shooter with no cracks in the stock, not much original finish on barrels and turning a brown patina, serial # 40## with 00 under the serial number, the man wants $1200.00 for it, i know it is hard to value a gun without seeing it but is this a fair price, any help appreciated
