Hey guys, I need a little help here. It has been pretty common knowledge that the Savage 340 series rifles were not serial numbered prior to the 1968 GCA. However in putting together my web article, http://www.leeroysramblings.com/Gun%..._bolt_act.html I have discovered that there are enough non-prefixed serial numbered guns out there to suggest that they may have indeed been numbered prior to 1960 as verified by the Chicopee falls address. These would have had to pre date the GCA act of 1968.

Can anyone verify this, & if so at what start date/serial number, AND the stop date in 1969?
