Hi,
I need some help,

.
I just obtained a P38 ac 43 but I'm in doubt about it and I have 3 days for inspection.
I compared it with a video that's at this website called 'ReplicagunsDirect.com' And it matches the Real one except in one respect. My gun has right above the trigger stamped 'Carpentersville, IL'. Does anyone have any idea what this means? Also, it appears to have been dipped to cover rust or pitting?
Any thoughts on it would be appreciated

Manuel
