[Channing Greene, Sr]

Putting it all together, it appears that my gun, at some point in time, had the original barrels changed, and presumably not by Parker. Possible culprit: my father's brother was a machine shop owner and a gunsmith. But why would he change? Original barrels damaged? Change from 16 or 20 ga?(Can that even be done and keep the original action?) Unfortunately both individuals are long-deceased, taking the secret with them. I do know that Dad was quite successful in partridge population control in Vermont in the early '30s, using this weapon.
Assuming the gun is in good condition, which it is, can anyone give an idea of the price range it would bring?
