Please bare with me, I am new to this. I have a Model 1897 Winchester 32 inch barrel 12 Gauge Shot gun, serial number 317006, condition unknown. It has a few blemishes, the for-end part of the wood is cracked a bit, (about 1 inch) but not enough to cause it to fall off. I do not know the last time it was shot, nor could the previous owner. I believe it is a 32 inch barrel, I measured from the tip of the barrel to where the back of the shell would be had it been loaded. I was visited oldguns.net and it's database said the gun was manufactured in 1907, I'm assuming this is correct? It also has a Black Dimond on the stock of the gun, near where the it connects to the barrel, do all 1897 Model shotguns have this or does it signify a higher end series? I am looking for a guesstimate of its value, granted it needs to be appraised, I am looking for rough ball park, so I am not going in Blind. Thanks for you help.
