Browning used a small ring intermediate Mauser action for awhile in the 60's, I believe, for short cartridges. If not, then it should be the Sako 579 action without the integral dovetails. You can easily tell as the front and rear rings will be the same height. Don't think it is the Sako High Power as that was earlier and was a long 98 FN action. By the 1960's Sako was using the L61 long action rather than the FN. Nice action whichever one it is.
