Well I own both, personnally I like the pre 64 best. New Model 70 trigger is not near as good. Action is not as smooth (this could be because the pre 64 is a '55) The fit and finish is better on the pre 64. Scope mounting to me is the same, buy the right mounts and all is good, can't see one is better than the other. The pre 64 is more accurate, could be an example of one. I do know that the pre 64 will not be worth any less as the years go by.
