AHhhh, I see it now.. thank you for that. I've been reading a lot on this and it seems as you are correct that its common to find the "UNITED STATES PROPERTY" and that doesn't necessarily mean that it was liberated. Although I would agree why bother if there were no reason to remove it.
Makes me wonders, how much does scrubbing the "UNITED STATES PROPERTY" off devalue the handgun? I don't even know what the value of these are in the first place the prices are all over the place. I hate it want people say make me an offer.. I feel like saying okay $50.00
