Hello Folks!
Thank you, for all the good answers.
First of all, I formally have to make clear, that I do not know a sh*t about Lugers.
I wanted to own one, for very long time - but the prices are a little to high for me, so that's why I purchased this one
I would very much like to answer all of you, but in the end, you can read the different comments.
1: I don't know, if it's an artillery model - but because of the 1917, I found this group, for WW1's. How can I see, if it's an artillery model, or not?
2: The condition, for me to say, is quite okay. My girlfriend is at her family now, and her camera is much better than mine, so in the morning (sunday, tomorrow) I'll post a few good pics of the gun!
