Welcome to the forum.
Look at our Lugerforum FAQ document and you'll start to see some of the details that are important.
search "FAQ PDF update" and you'll hit the post. There is a lot of good reference informaton.
You need to use a camera that will focus and allow good sharp pictures of details of your pistols. We need to see those details and also the condition of the guns and their finish. Take the pictures in natural shaded sunlight without a flash (it washes out the finish appearance).
You access quite a bit of experience and expertise on this forum. You are working on the photos for your benefit, not ours.
The pictures of your 1915 DWM Luger are sharp enough to declare that this pistol has been through an aggressive buffing process with an abrasive, and then finely polished and refinished. Sadly, this takes away all collector interest and 50% or more of value.
This Luger would be relegated to the Shooter category in most collections. But for that purpose of having fun at the range, it is fully desirable. So, if it passes a safety inspection, take it out and shoot it with some standard loads. If a part breaks, no big deal. You can replace the broken part without any risk of losing value to your gun.
