Gents,

For a 70 and 670 built in the late 60s or early 70s, are the only real differences the stock (wood type), safety (2 vs 3 position), and the bolt not being jeweled on the 670? I.e., am I correct in understanding that action, trigger, and barrel are all the same and the above are what made the 670 a little cheaper?

Thanks y'all!
