WWI luger to WWII?

[jeffs]

Dear Experts

Is it possible that a WWI Luger with all the proper imperial markings could have also served in WWII without getting any additional Weimar or Nazi era marks or proofs?

Is it possible for a Luger to wind up in VOPO service without any evidence that it had been first in Russian hands (dip refinish or X's)?

Thanks,
Jeff
