What is the value of a Winchester Model 94 Nickel Steel 25-35?

The Model 94 Nickel steel 25-35 is a VERY RARE GUN. when the 25-25 was introduced it was primarily used in safari grade rifles ie,double barrel rifles,so if you have acquired a lever action one (i am assuming being a winchester) than i would take it to somebody who is very familiar with older model guns because the gun is not in production any more--and neither is the round-
