Anyway, an 1886 will be going up on the auction block locally in a few weeks and I've been looking for information on these rifles, as I'm potentially interested. The condition is described as being "excellent" and it is chambered in the .40-82 cartridge. I looked up the serial number (in the 30,000 range) and think it was manufactured in 1889. I don't think they really know much about guns so I'm a little leery of the "excellent" descriptor and there is only one picture of it available online, however it doesn't look terrible to my eye. The pic isn't the best so it is hard for me to tell for sure whether or not it has been refinished.
For those of you more experienced with these rifles, what should I look for in evaluating it? What kind of $$$ do they typically bring? I imagine there are probably a lot of variables involved in determining valuation but what is a ballpark range between shooter and collectible? I know Winchesters, especially from this era, are incredibly popular so I'd be surprised if I go home with this one, but I'd at least like to be prepared.
Here's the only pic I have:

To me, the metal looks like it might be okay, but the shine of the stock concerns me a little though it doesn't look to be a total disaster. I can't tell if the (round, not octagonal?) barrel is missing bluing or if that is just a glare I'm seeing.
