I have an opportunity to purchase a 30/30 winchester 94 that's over 100 years old. As far as I can tell, its all origional and in good to very good conditon. The price is very reasonable. Any idea on value? Any doubts it could be a fake?

Impossible to answer without details. Carbine, rifle, short rifle, LW rifle, solid frame/takedown, Oct/round, Musket, finish, caliber, sights, and God knows what else you can supply for info. Fake as in ?
