What is the age and value of a Winchester Model 94 with an octagon barrel and serial number 164458 in very good condition?

Your serial number indicates that your Winchester model 1894 rifle was made in the year 1899.Being such a early model 1894 rifle,I would have it appraised by a member of the Winchester collectors assoc.It could bring in the neighborhood of 1,500-2000 dollars in the condition you describe.Especially if it has any special order features which could be ordered in that time.These would include checkered wood,special wood,half magazine,octagon barrel,special barrel length,a take down model etc.
