Commercial, large ring Mauser '98 (no thumb cut f/stripper clip charging) .
Bolt is an FN commercial bolt. The proof stamp at the top of the bolt handle proves that. Most commercial FN bolts were flat and knarled on the bottom side.
If the bolt matches the action, the action is also a FN, could be a JC higgins model 50 or something which is the sears version of a restamped FN.
Some of the earlier FN commercial actions came with the Military style bolt shroud. I have a couple that look just like it.
Good note of the safety, that would be something to get fixed.
