Wiemer military property markings?

[Stevie]

I own a 1920 dated DWM P08 4" 9mm. This gun has no unit marks or "made in Germany" markings. She also is proofed with the Weimer dove proofs. I always figured it for a well worn and pitted German Army pistol. It is a gun that was imported a few years back

In front of the doves the pistol has a compact geometric stick eagle. On the left rear of the barrel is another stick eagle that is more eagle looking, with wings and tail feathers. These are not like the Nazi era stick eagles as on my Mauser 42, and are not represented in the Luger proofs in the tech info section.

I tried a picture but the eagles wouldn't show, as the gun is pretty hard used and refinished a time or two.

I know the 1920 date is a sort of property mark. What might the above described stick eagles represent?

Thanx,,Stevie.
