Same response as my post at P.38 forum:
Well, you have asked a very complex and deep question.
My recommendation is that you study Lugers by getting copies of the literature before you consider buying anything.
A collectible gun should run between $1500 and the moon these days depending on a large number of factors.
A shooter should be between $850 and $1400 depending on a large number of things.
You can start to get an idea by downloading the LugerForum FAQ document, and then checking online sales from reputable dealers.

Most of us won't click links to offsite photos (you can upload pictures here), and these photos are not that well lit so it's hard to judge what you're looking at.
What are they asking for it?
