Wakeenee, your post probably will be moved to the New members section as there are other posts like this there. As far as type of variation, and other information, we need to either(or both) see a detailed description of condition, proof marks and other identifying attributes or pictures that detail those features of your Luger. (Borrowing from anther post in that section....)
Your gun's currrent market value is dependent on its rarity, market demand for the model you have, original condition, any accompanying accessories and often its proveable history...
There are Luger Identification sheets in the Technical information pages of this website. when you have collected all the information asked for on these sheets, post the information here, (photographs are optional but encouraged and helpful) and you will be pleasantly surprised to know that those members who can educate you about its origins, history and current value will be glad to help you.
