Beat up 1911 DWM. Rework???

[nnickons]

Hello all, I am a long time milsurp collector but new to Lugers.

I Picked up this pretty beat up 1911 DWM pretty cheap and have a few questions about it's history. The gun came out of an estate, and is definitely a bring-back but I'm not certain when it got here. It seems to have an Erfurt(?) frame and a Simson sear, it is also not 1920 property marked.
Now I'm not necessarily a "Luger guy" so hopefully some of the more enlightened among you can get me learnt on what's going on here.

All numbers (that I can find) match except
- trigger
- takedown lever (unnumbered)
- hold open (unnumbered)
- grips (WWII production, marked "S" with an eagle/655)
- sear, marked eagle/6

Barrel is either unnumbered or the number has been obliterated by time (looks like possible "n" suffix still visible. The suffix (if there ever was one) is gone from the frame.

Thanks in advance for the help, it's great to be among the expertise of so many knowledgeable people
