Identify this Luger

[Andre']

Hello,

pretty much my first post here - I'm getting serious about purchasing my first Luger. This one is not exactly what I've been looking for but - somebody offered me this one - and I'm just looking into it. She looks pretty rough but I think it's an early model - the BUG proof marks are present, and all numbers are matching except the mag (has a serial # although there shouldn't be one). No date stamp, no stock lug, no grip safety. Overall, she looks pretty aged, and the grips have some damage marks as well. My big question - what exactly is it (I believe 1908 commercial) and what is a fair price for a luger that's all (almost) orginal but has seen some use over the years. Thanks!
