Art,
As others have indicated, you have a very nice collectable Luger. Just a few suggestions:
1. As recommended, clean and lubricate the gun to preserve its fine condition
2. The ammo boxes are collectable items also, so remove the rubber bands as they will deteriorate and stain the paper lables. Remove the string as well and wrap the boxes in plastic kitchen wrap to maintain their condtion.
3. Empty the ammo from the magazines so that the springs are not further stressed. Magazines are not made for long term storage.
4. Sell it to me
Best regards,
Ron
