I sold a near mint half-pistol grip 12-gauge 28-inch 4-weight Chromox barrels A-Grade from 1920, with the hang tag, four years ago for $1500. I'm sure the reason it stayed near mint was its over three inch drop-at-heel. It was a great example of the cynide case colors of the period. There has been more increase in the price of 12-gauge Fox doubles in the four years since I sold it then in the 11 years I owned it!
