Just a bit more info--  The bottom metal (trigger guard and floorplate assembly) appear to be from a M70 Winchester, not unusual at the time.  The period is almost certainly from the '70s as I have one I built that is exactly the same style,, difference action but the stock style is very similar.  The wood appears to be a streaked piece of english walnut.  Mine is a 300 WinMag and these stock while the style has gone out of favor, a more comfortable to fire than some of the 'clasics' we see today, especially with a heavy kicker..  Flaigs was a pretty well respected shop and did quite a business.  In 6.5x55 there should be nearly no recoil and it's a great deer, bear rifle.  The caliber is used heavily in europe for nearly all game including what we call moose.  Great rifle in a clasic caliber..
