A marvelous thing indeed! No wonder people are often asking if a photograph has been Photoshopped. You've made it look much more like it really is. The mill marks and everything seem clearer too. Here's the left side, with the action open.

And while this is off topic, perhaps I may be permitted to bring this up here. Is it in any way harmful to leave a Luger with its action open for a lengthy period of time? For instance, while we have an empty nest, this Luger may eventually spend time with a family member with children, and they would be keeping the pistol with the action open and one of those DAC cable locks through the barrel and breach.
