Eagle over swastika, same as was on a wartime Hi Power I once had.
On the receiver ring, at about 1 o'clock looking toward the front sight. Barrel is also stamped, same position.
Under the eagle, the letter NOAB appear.
From 9:00 to 12:30 is stamped Nb 1944-531 on both receiver and barrel.
At 2:00 the eagle is repeated, but slightly larger, both on the receiver ring and the barrel, with no letters.
At 3:00, the smaller eagle with the letters appears again on the receiver, but not on the barrel.
These markings are really not all that faint, I just never looked at them carefully enough to recognized then for what they are. Too embarrassed to admit it.

Bolt handle has the number 1073 on top, and what might be a stylized dragon with a wavy tail.
Magazine cutoff has letters AA on top, and letter S underneath.
Neat Williams receiver sight installation, and a ramp front. It has been reblued, Remington plastic buttplate. Might be a cleaned-up issue stock.
Chambered 6.5 x 55. Haved never fired it myself. On cleaning it after I got it home I found the first 2-3 inches of the bore to be a bit too rough to shoot cast, which is what I like to do. So it's been a safe queen for all these years.
