Welcome Alexs!
The grips should have very little put on them, less is better than more (i.e don't oil soak them). I cleaned mine, using Murphys Oil Soap, then put linseed on them.
Can you tell us any other markings on the gun?
Proofs? (see on your left under tech information if you came through
www.lugerforum.com) Tell us what and where proofs and markings are located.
There are forms in this section, where you can print out and then write down pertinent information.
What serial number is on the gun? To include any letters next to or under the serial number?
Can you provide pictures, to include side, top, etc?
