Thanks, Michael...extractor markings on both sides is as it should be.
Congratulations on your find. You have a very desirable and envious Luger !!!
If you are looking for a holster, I have attached a photo scan of the "Dutch" holster that is proper for your gun...in case lightining strikes twice and you are lucky enought to find a holster as well...
Last one I saw that sold about a year ago went for $ 700...in good condition...
