Winchester, like Savage, were cutting costs in the mid 1960's.
There's lots of info on the net about what exactly they did, such as cheap finish, machine impressed checkering, stamped metal parts etc etc.
Avoid Winchester 94's made between 1964 - mid 1970's, after that, they got better.
I prefer the pre 1952 Winchester '94's with the "long wood" ahead of the for end, they look more "classic".
