What is a 1904 Winchester model 94 30-30 in excellent condition worth?

That all depends on the rifle it self.Do you have any special order items such as a half magazine,special wood,checkerd wood,octagon or half round half octagon barrel,length of the barrel etc.All these will raise the value of your rifle.I myself would not except any less than 850 dollars for it.It may well be worth more with any of the above noted features present on your rifle.Also consider if it is a carbine or rifle,and if it has a shotgun style butt stock,or cresent style butt stock.
