halfdar...........I have been a collector for some time now and what your buddy has is a very common rifle in good condition. The pictures leave some points uncovered but it appears to be very good. This rifle would value between 600-750 dollars from what can be seen in the photos. Don't let others tell you it's worth a fortune because they just are not, they are too common in this cartridge...........in this condition in 25-35 is a whole different ballgame, but it's in 30 WCF, the most common of all.
This is pretty close to what I think as well, though I'll caveat it that I have not seen the butt plate or a clear picture of there the wood meets the receiver to ensure it's not been refinished.
At my local gun store, I think it would be listed around $850 or so.
Sad but true that you could put a regular tangent sight off another 94 on that gun without much affect the value and that leaf sight would sell for about $200USD by itself on e-bay.
