Question on a winchester model 97 shotgun?

I just recently was willed my step fathers shotgun and was wondering if anyone might know what it might be worth. It has a medium tone wood stock and is a 12 gauge full choke shotgun. He always used it for deer, rabbit, and pheasant hunting. It is in pretty good condition. I dont know much more info to give on it other than it has the writting winchester 97 on the side and again on the barrel also says 12 gag full on barrell and has a 6 digit number on the underneath. will give best answer for this question thank you
