A lot of us here can tell you when it was made if you give the serial # putting X's for the last couple of numbers to protect yourself. Otherwise yes Rule's book will also get you dates of mfg. There are a lot of online sources and other books for this too.
They only made around 600,000 pre 64 M70's so all but the first 99,999 of them are 6 digit serial numbers.
