What records perform exist leave part room for interpretation about the specific production date of any type of given pre-64 version 70.
In the lack of factory records, it might seem reasonable to regard the date stamp under the room area of the barrel together a method to day a rifle (these stamps were present on the design 70 until 1956). However, this stamps indicate the year that barrel production only, and also not the rifle. Barrel production preceded the rifle and these barrel dates typically precede the manufacture day of the rifle by a year, and sometimes by plenty of years.
