Just curious what I can find out about this stamping. It appears an Export stamp for commercial Lugers destined to be sold in the USA. My question is was the stamp applied after the gun was blued or reblued. I would assume it would show up in the white if on a WWI rebarrel model, but what about new commercial Lugers, would the stamp be applied after the gun was rust blued? I have not thought to really examine this marking before on examples with original finish. Thanks for any help on this marking.
