What is the value of a Winchester Model 1866 Saddle Ring Carbine repeater 4440 caliber Rifle?

A original Winchester model 1866 fourth model carbine will bring between 3,000-8,000 for a rifle in below average condition,8,000-20,000 for a average condition rifle,and 20,000-35,000 dollars for a above average condition rifle.I would very seriously consider having a member of the Winchester collectors assoc.evaluate and appraise this rifles value.
