difference between pre and post 64 m70s

Just bought a model 70 in 270 win and it looks pretty old. how do i tell if it is a pre 64 or not?

If the bolt has a Mauser-type extractor, it could be a pre-64, or post 1991. Push-feed style was made in those years between. If your serial # has a "G" before the numbers, it was made after 1968.

There are many differences between the pre, and post 64 model 70. The most obvious difference is the extractor and ejector setup. The pre 64 has a large claw extractor that covers the right locking lug when the bolt is extracted, and the ejector is a fixed system through a cut in the bolt face. The post 64 has an extractor that is mounted within the right locking lug, and the ejector is a plunger-type that appears as a round sprung button within the bolt face.
