Which book ?

[HuntMaster]

Thanks for the quick replies.
I suppose I am looking for a general overview. As I increasingly learn to love the Luger, I would like to be able to identify these pistols if and when I find them at gunshows, etc.... .
I have been proud of my 1st two purchases, as I feel I got them at the right price, and want to be able to spot a fake ,or know what to pay for different makes, or if I spot a seriously undervalued treasure.
I'll take a look at these suggestions.
Also, I recently purchased a 1917 Artillery model, which according to some info out there on the web , many were destroyed after the war, or had shorter barrels installed, thus ruining the guns. I would have thought the gun was worth far more than the $1200 I paid, even if it was a low-grade shooter, based on some of the info circulating the world-wide-web.
I have since perceived that this find is somewhat common, and therefor may not be the prized possesion I would have thought before joining this forum.
So far, this forum has been a great source of information, but sometimes I just want to kick back and read in my easy chair.
