Another new Owner

Sn 6865s would be at the beginning of Mauser switching from rust blue to salt blue. I have seen many salt blued Lugers in this time frame with the glossy/matte areas near the chamber date. Mauser hadn't perfected the salt blue process yet. From the picture provided the magazine looks good to me.
Here is another example of a early salt blued 1937.
