William,
If your Arty is going back into storage, I would suggest some treatment to curtail what appears to be some serious rusting over the gun's finish.
If you do a Luger Forum "search" on the word "rust", you will probably pick up some very useful advice that some of our sage collectors have posted in recent months...
Regards,
