Hello,you guys have been very helpful.I need to bother you all one more time.My brother has an old shotgun it's a winchester 97?I THINK??It's a pump action 12 ga. with an exposed hammer.What the hell kind of cockeyed setup is this?My brother has fired it and it seems to work fine.What is the value of this gun?What does 97 stand for a year maybe?It has a 20 in. barrel if that helps any?Are these good guns?IE:well made?easy to find parts if you need them?Or is it one of those great guns that almost never break with normal use and care?As always thanks for any help.
