I have several pre-64 94's, and a new "Angle eject" Trails end in 44 mag. I've also owned a couple of other "post 64" 94's over the years. When Olin bought Winchester, they were run by bean counters, who tried to squeeze every nickle out of the company. Olin changed the material of the receivers, and used stamped steel parts instead of forged. If you ever see a Plum colored receiver, that is a post 64 that has been attempted to be reblued. The fit and finish was poor. If you get a chance try the actions of the two different rifles and notice the smoothness of the pre 64.
Saying that. I noticed when USRA obtained manufacturing rights to Winchester, the quality has improved greatly. I believe that they have gone back to a forged receiver, they stopped using stamped parts, and returned to forgings. I recently obtained a "Trails End" SRC in 44 mag. I got a Williams FP receiver sight from Brownells, and installed it. When I took it to the range I was pleasently suprised. With my Hand gun load of 20.5grs of 2400 with a Hornady 240 XTP it shot less than an inch at 100 yds. I don't like the Lawyer mandated cross bolt safety, a item that is not needed, but the fit and finish is very good. I think that I'll probably hunt with this rifle this fall.
I hope that this helps
