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.
