What is the value of an Oxford Arms Company double barrel shotgun?

I have an oxford arms 12 ga that was my grandfathers after many years of looking the only info i have come up with is that the guns were produced by the crescent for belknap hardware company in louisville KY around the early 1900's the only values ive seen were in the $300-$400 range and it seems as though the hammerless versions were worth more(with steel barrels rather than damascus)the crescent fire arms company was in norwich conn. est. around 1892 and was purchased by h & d folsom in 1893 and asorbed by Stevens arms & tool in 1926.if anyone else knows anything about these guns i'd like to know as there seems to be little info or history available.
