Inherited a 1910 Luger DWM, Trying to Learn More About It

[Geo99]

That looks like more than surface rust to me - I see a lot of pitting.
I'm sorry but this gun can't be worth more than $900 in that condition. The only thing that would make it worth more is if the mags are numbered to match the gun.

In my experience, rust damage is somewhat permanent and can never be fully fixed. I've ruined more guns with bronze wool than I care to admit. It leaves the bluing with a yellow or gold tint. Stick with CLEAN oiled steel wool and you should be able to turn the rust dark enough to blend with the finish. After that, the best thing I have found to remove any remaining rust safely is a Q-Tip soaked in gun oil and a lot of rubbing. Keep rubbing and checking - as long as the color of what you are removing is brown, you are OK. As soon as you see gray, STOP - that is bluing coming off.

Still, it's an original Luger for someone to start out with and learn by taking it apart and putting it back together a few times.
