Luckily, my father just gave me his grandfather's Luger. I got some information from another luger website, I was told this gun was referred to as the "black widow". He also gave me the gun with a holster from WW1.
The only unfortunate part is that he has lost the magazine for the gun.
I have some pictures posted at my photobucket account.

Any information available on the gun is very helpful. I believe the gun has all original #'s matching parts, and grips appear to be original aswell.
Thanks for any help in advance!
